When Texans running back Arian Foster threw his helmet in disgust after going down prior to contact on a run against the Eagles on Sunday, you knew something was wrong. It turns out Foster again is dealing with another leg injury, this time to his groin.

The extent of his injury won't be known until an MRI on Monday, but there are differing reports on the severity. CBS Sports NFL Insider Jason La Canfora said the injury isn't serious, but ESPN said there's some concern for Foster, who missed Week 3 against the Giants with a hamstring injury.

The good news is the Texans are off in Week 10, so hopefully Foster has time to heal. In the meantime, every Fantasy owner needs to add Alfred Blue off waivers, and his ownership is 24 percent on CBSSports.com leagues.

Foster wasn't the only big injury in that game, as Eagles quarterback Nick Foles suffered a broken collarbone on his left, non-throwing shoulder. He could be lost for the majority of the season, which would open the door for Mark Sanchez to start for Philadelphia for the foreseeable future.

Sanchez is owned in just 1 percent of leagues on CBSSports.com and would be a serviceable No. 2 Fantasy quarterback and bye-week replacement, especially in Week 10 against Carolina. There might not be much of a dropoff in production from Foles to Sanchez based on how this offense allows quarterbacks to have success.

Quarterbacks

Player on the rise

Carson Palmer continues to prove he's an awesome Fantasy quarterback this season, and he was great as our Start of the Week. He was 22-of-34 passing for 249 yards, three touchdowns and one interception at Dallas for 25 Fantasy points. This is now at least 20 Fantasy points in all five games he's played this season -- and 25 points in two straight. He faces the Rams at home in Week 10, and he should continue to stay hot with another 20-point outing.

Player on the decline

Russell Wilson is starting to fall apart as a Fantasy quarterback. He was 17-of-35 passing for 177 yards and eight carries for 31 yards against the Raiders for 10 Fantasy points. Let that resonate for a little bit, because it was against Oakland at home. He now has 14 Fantasy points or less in three of his past four games, and it might be time to bench him even in favorable matchups. He faces the Giants in Week 10 at home, and he should be considered just a low-end starting option at best based on his recent low level of play.

Quarterback injuries: Nick Foles (collarbone), Philip Rivers (hand)
Quarterback waivers: Ryan Tannehill (70 percent ownership), Robert Griffin III (66 percent), Alex Smith (60 percent), Brian Hoyer (29 percent), Michael Vick (26 percent), Kyle Orton (25 percent), Mark Sanchez (1 percent)
Of note: Tannehill is another quarterback on the rise following his performance against the Chargers on Sunday. He was 24-of-34 passing for 288 yards and three touchdowns and four carries for 47 yards to finish with 33 Fantasy points. This is now at least 21 Fantasy points in four of his past five games, and we're buying into Tannehill as a potential starter in all leagues. He has a tough matchup in Week 10 at Detroit, but he's in the discussion as a Top 12 quarterback based on his recent success. ... In that same game, Rivers was terrible at Miami. He hurt his hand in the game, but the injury is not considered serious. He finished 12-of-23 passing for 138 yards and three interceptions. We hope Rivers will do better in Week 11 against Oakland following San Diego's bye week. ... We're glad the snow didn't ruin the game for Peyton Manning and Tom Brady in New England. Brady was better with 35 Fantasy points, but Manning was still solid with 25 points. Brady is off in Week 10, and Manning should have a huge game in Week 10 at Oakland. ... Griffin returned from his six-game absence with an ankle injury at Minnesota and was 18-of-28 passing for 251 yards, one touchdown and one interception, and he added seven carries for 24 yards. The Redskins are off in Week 10, but it was good to see Griffin get through the game without a setback. He could be a great starting option in Week 11 against Tampa Bay if you're looking ahead. ... The Jets have said Vick will start again in Week 10 against Pittsburgh. It's not a bad matchup for Vick, who had 14 Fantasy points in Week 9 at Kansas City. He's a viable option in two-quarterback leagues. ... Colin Kaepernick was one of the biggest disappointments of the week after he had just 12 Fantasy points against the Rams at home. The offense was out of sync, and we hope they can turn things around for Week 10 at New Orleans. But based on how the Saints have played at home and how bad San Francisco looked against St. Louis, I'd be hesitant to start Kaepernick in the majority of leagues. ... The Cowboys are hoping Tony Romo (back) can start Week 10 against the Jaguars in London after he was inactive against the Cardinals. They need him after Brandon Weeden was awful with 18-of-33 passing for 183 yards, one touchdown and two interceptions for nine Fantasy points.

Running backs

Player on the rise

Jeremy Hill started for the injured Giovani Bernard (hip) and was stellar against the Jaguars. He had 24 carries for 154 and two touchdowns and one catch for 9 yards. The Bengals play the Browns on Thursday night, and it's unknown if Bernard will play in that game. If Hill starts, he's a No. 1 running back in all leagues. Now, when Bernard returns, we expect this to be a tandem moving forward. Hill deserves work, but he's not going to replace Bernard as the starter. But the better Hill does the worse it is for Bernard as a featured option.

Player on the decline

Ben Tate might be done as the starter for the Browns, or at least his time as the featured option is dwindling. He had 10 carries for 3 yards and four catches for 29 yards against Tampa Bay. Meanwhile, Terrance West had 15 carries for 48 yards and one catch for 2 yards and a touchdown. Isaiah Crowell didn't touch the ball against the Buccaneers, but Cleveland needs to inject some life into the running game. You can't completely blame Tate since the Browns are missing standout center Alex Mack (leg), but something needs to change after Tate has been held to 41 carries for 65 yards and one touchdown in his past three games. I wouldn't drop Tate yet, but I would add West (33 percent ownership) in all leagues.

Running back injuries: Arian Foster (groin), Lamar Miller (shoulder)
Running back waivers: Bobby Rainey (81 percent ownership), Denard Robinson (81 percent), Tre Mason (59 percent), Bryce Brown (50 percent), Charles Sims (37 percent), Matt Asiata (34 percent), Terrance West (33 percent), Alfred Blue (24 percent), Daniel Thomas (6 percent), Chris Polk (1 percent), Damien Williams (0 percent)
Of note: We hope Miller is OK after he left Sunday's game in the third quarter with a shoulder stinger, and he's headed for an MRI. He finished with 11 carries for 45 yards and a touchdown and one catch for 8 yards against the Chargers. If he's out for Week 10 at Detroit, look for Thomas and Williams to split touches, and we'd look at Thomas first off waivers. ... Welcome back, Marshawn Lynch. He dominated the Raiders with 142 total yards and two touchdowns for 25 Fantasy points, which ended a three-game stretch of single digits in Fantasy points. He should play well again in Week 10 against the Giants. ... The Redskins proved to be a tough opponent for Jerick McKinnon, who was held to 14 carries for 54 yards and three catches for 14 yards, but his biggest detriment was teammate Matt Asiata, who had 10 carries for 26 yards and three touchdowns and four catches for 31 yards. We still expect McKinnon to be the best running back in Minnesota moving forward after the Vikings' Week 10 bye, but Asiata showed he still has some life as a Fantasy option with his performance this week. ... Robinson stayed hot at Cincinnati with 17 carries for 94 yards and a touchdown and two catches for 10 yards. This is now three games in a row with at least 11 Fantasy points, and he should do well again in Week 10 against the Cowboys in London. Dallas has allowed two running backs to reach double digits in Fantasy points in the past two games with Alfred Morris and Andre Ellington, and Robinson should be considered a must-start option moving forward until someone stops him. ... The Buccaneers went away from Rainey in the second half at Cleveland, but he still finished with a solid stat line of 19 carries for 87 yards and one catch for 34 yards. Sims is expected to make his debut in Week 10 against Atlanta, but Rainey should remain the starter as long as Doug Martin (ankle) is out. However, Sims will likely get an extended look soon, so Rainey's time as a viable Fantasy option is limited. ... The Jets went away from Chris Ivory at Kansas City, and he finished with just eight carries for 22 yards and no catches. Chris Johnson got hot in this game with 11 carries for 69 yards and two catches for 32 yards. I'd still rather have Ivory heading into Week 10 against the Steelers. ... The Rams stuck with Tre Mason against the 49ers, and he finished with 19 carries for 65 yards and one catch for minus-8 yards. Benny Cunningham added four carries for 10 yards and three catches for 38 yards, and Zac Stacy did not touch the ball. I wouldn't use Mason in Week 10 at Arizona, but he's still worth stashing on your roster. ... Frank Gore had a streak of 13 games in a row with a touchdown or 100 total yards at home snapped against the Rams when he had 14 carries for 49 yards and one catch for 9 yards. He now has 39 carries for 107 yards and no touchdowns and one catch for 9 yards in his past three games, and I wouldn't start him in Week 10 at New Orleans. ... It's probably time to cut Branden Oliver, who was held to 13 carries for 19 yards and one catch for 7 yards at Miami. He could still have a role with the Chargers moving forward, but they have a bye in Week 10 before Ryan Mathews (knee) should return in Week 11. Oliver now has just 13 Fantasy points in his past three games, and San Diego will almost certainly give Mathews a heavy workload when healthy.

Wide receivers

Player on the rise

Mike Evans is starting to establish himself as the No. 1 receiver for the Buccaneers. While Vincent Jackson snapped out of his recent funk with six catches for 86 yards on 12 targets at Cleveland, Evans had seven catches for 124 yards and two touchdowns on 11 targets. He now has at least seven Fantasy points in each of his past four games, with 11 or more points in three of those outings. He should have the chance for another solid performance in Week 10 against Atlanta, and Evans should be 100 percent owned in all leagues this week.

Player on the decline

Michael Floyd's disappearing act continued Sunday at Dallas with four catches for 36 yards on five targets. He now has 47 yards or less in each of his past five games and just 12 catches over that span. His saving grace was a touchdown in two of those games, but Fantasy owners have no confidence in starting him in Week 10 against the Rams. Now, I would actually give him another chance against St. Louis based on the matchup, but I can understand being hesitant. Palmer is spreading the ball around, and four players had at least five targets against the Cowboys. If Floyd doesn't come through against the Rams then he should remain benched in the majority of leagues until further notice.

Wide receiver injuries: Wes Welker (back)
Wide receiver waivers: Odell Beckham (79 percent ownership), Mike Evans (71 percent), Martavis Bryant (67 percent), Jordan Matthews (37 percent), Justin Hunter (34 percent), Davante Adams (31 percent), Kenny Stills (24 percent), Allen Hurns (14 percent), Kenny Britt (11 percent), Jarvis Landry (5 percent), Taylor Gabriel (1 percent), Rishard Matthews (1 percent)
Of note: Hopefully Welker will be OK for Week 10 at Oakland, but even if he plays you can't count on him as a reliable Fantasy option. He had three catches for 31 yards on seven targets before hurting his back and now has 60 yards or less in all six games he's appeared in with only one touchdown. ... Jeremy Maclin had another huge game at Houston with six catches for 158 yards and two touchdowns and has now scored in six of eight games this season. He caught a touchdown from Sanchez and shouldn't be impacted by the quarterback change. ... Hurns had his second game of the season with two touchdowns, as he finished with seven catches for 112 yards and the two scores at Cincinnati on a team-high nine targets. The last time he scored twice in the same game was Week 1 at Philadelphia, but he scored just one other time in between. In seven games this season he's finished with 70 receiving yards or less, and he's the definition of a boom or bust Fantasy option. I'd still rather have Allen Robinson, who was held to four catches for 35 yards on eight targets against the Bengals. ... DeSean Jackson did not slow down with the return of Griffin, and Jackson had four catches for 120 yards and a touchdown on seven targets against the Vikings. He now has at least 115 receiving yards in five of his past seven games with four touchdowns over that span and should continue to thrive after the bye in Week 10. Pierre Garcon, meanwhile, was held to three catches for 15 yards on five targets against the Vikings. He now has single digits in Fantasy points in five of his past six games, and he's getting close to being on the dropped list. ... Vick might not have been great in his first start this year, but he did get Percy Harvin going with 11 catches for 129 yards on 13 targets at Kansas City, and he also added one carry for 8 yards. We hope this is a sign of things to come, and Harvin could end up being a tremendous Fantasy option if this is his expected workload moving forward. Eric Decker also added nine catches for 63 yards and a touchdown on 12 targets, and both Jets receivers are now in play for Week 10 against the Steelers. ... Anquan Boldin tormented the Rams once again with six catches for 93 yards and a touchdown on seven targets. We just wish he was more consistent against the rest of the league. His only two games with double digits in Fantasy points this year have been against St. Louis. Michael Crabtree finished with five catches for 40 yards on nine targets, and he just missed a touchdown in the fourth quarter when he was stopped at the 1-yard line. Two plays later, Kaepernick fumbled, and the 49ers lost. ... A.J. Green returned from his three-game absence with a toe injury and had three catches for 44 yards and a touchdown on six targets against the Jaguars. He should be locked into lineups for the rest of the season barring another injury. Mohamed Sanu also stayed hot despite Green's return. He had four catches for 95 yards and a touchdown on eight targets, and he now has double digits in Fantasy points in a standard league in every home game. Keep that in mind for Week 10 vs. the Browns. ... Julian Edelman had the breakout game my colleague Dave Richard was expecting against the Broncos with nine catches for 89 yards and a touchdown on 10 targets. The touchdown was his first since Week 2, and he ended a two-game slump against the Jets and Bears where he combined for five catches for 58 yards. We hope this is the Edelman we'll see each week after the bye in Week 10. Brandon LaFell also stayed hot with six catches for 53 yards and a touchdown on 13 targets, and this was his first game with double digits in Fantasy points in consecutive outings this year.

Tight ends

Player on the rise

Travis Kelce showed once again that when he's involved he can be a difference maker. He had four catches for 67 yards and a touchdown against the Jets on five targets, which was second on the team behind Dwayne Bowe (10). He's now had five targets or more five times this season, and he's finished with at least eight Fantasy points in three of those games. Give him the work, and we're confident he can reward Fantasy owners with a solid stat line.

Player on the decline

You can safely drop Jordan Reed in the majority of leagues. He had one catch for 17 yards on one target at Minnesota, and the Redskins are on a bye in Week 10. Reed now has 13 catches for 111 yards and no touchdowns in the past three games since he had eight catches for 92 yards in Week 6 at Arizona in his return from a four-game absence with a hamstring injury. You can probably pick him up again in Week 11 with the hope he finishes the season strong, but there's no reason to stash him at this point with his recent lack of production.

Tight end injuries: None
Tight end waivers: Charles Clay (40 percent ownership), Kyle Rudolph (29 percent), Mychal Rivera (4 percent), John Carlson (2 percent), Anthony Fasano (1 percent), Chase Ford (0 percent)
Of note: Rivera had eight catches for 38 yards and two touchdowns at Seattle on 11 targets and has turned in two solid games in a row after he had seven catches for 83 yards on nine targets in Week 8 at Cleveland. He is a great bye-week replacement for Week 10 against Denver. ... Clay now has two touchdowns in his past three games after he had five catches for 65 yards and a score against San Diego on eight targets. More consistency would be nice after he had one catch for 1 yard at Jacksonville in Week 8. ... Speaking of consistency, Timothy Wright was a non-factor against the Broncos with no catches on zero targets. He teased us last week with seven catches for 61 yards and a touchdown against the Bears but now has two games in his past three outings with no targets. ... Maybe Zach Ertz will benefit with Sanchez starting, but he had one catch for 4 yards on two targets at Houston. You can cut Ertz if you need tight end help heading into Week 10 because he has just two games on the season with double digits in Fantasy points in a standard league and has been a colossal disappointment.
