Bailey (calf) has been ruled out for Sunday's contest against the Bills.
Considering Bailey didn't practice at all this week, it shouldn't come as a surprise that he will skip another game Sunday. This week marks his third straight absence, and the combo of Jaye Howard and Dontari Poe will likely anchor the middle and the defensive end spot left vacant by Bailey.
Conley caught just one pass for six yards Sunday against the Lions.
Conley continues to go through highs and lows in his rookie season, seeing just nine snaps a week after catching six passes for 63 yards against the Steelers. His boosted production likely came due to the absence of Jeremy Maclin, and Conley will likely continue to have unpredictable outings moving forward that makes him an unreliable fantasy option at this point.
Ford (back) will not play in Sunday's game against the Bills.
Ford injured his back during warmups last Sunday, and it will cost him at least another week as well. Tamba Hali will continue to see the largest chunk of time at right outside linebacker, but Dezman Moses could be in line to spell him again Sunday should the veteran need rest.
Hali compiled his biggest game of the season Sunday against the Steelers, notching two sacks, five tackles (four solo) and one forced fumble.
He also added one additional tackle for loss in the effort, but Hali's five tackles matched his season high while the two sacks also represented his top output in that category. He'll get a chance to add to that total Sunday against a Lions offensive line that ranks around the league average in sacks allowed this season.
Kelce (groin/ankle) is listed as questionable for Sunday's game against the Bills, the Kansas City Star reports.
Per the report, Kelce, who practiced fully Wednesday and Thursday, suffered a "slight ankle sprain" Friday and missed most of the Chiefs' final workout of the week. Given the late-week downgrade, Kelce's status will need to be monitored closely in advance of Sunday's contest, which fortunately for his fantasy owners is a 1:00 ET kickoff.
Parker could see an extended run Sunday against the Broncos.
Parker saw his first game action with the Chiefs two weeks ago against the Lions, making key blocks on a play that led to a 10-yard touchdown run for De'Anthony Thomas. However, he didn't make have any grabs in the contest, and probably won't do enough even in his expanded role to be worth consideration in fantasy leagues.
Thomas (concussion) won't play Sunday against the Bills.
Having recorded 17 catches for 140 yards and a TD, to go along with nine carries for 34 yards and a rushing score in 10 games to date, the versatile Thomas is only of interest in deeper fantasy formats, though his absence does represent a hit to the Chiefs' Week 12 return game.
West (hamstring) is listed as questionable for Sunday's game against the Bills, the Kansas City Star reports.
The running back missed practice all week, but given that he "is making progress," per coach Andy Reid, the team hasn't ruled West out for Sunday's 1:00 ET tilt. At this point, West can probably be viewed as a game-time decision for the contest, with Spencer Ware presumably next in line for the Chiefs' Week 12 carries, should West be made inactive Sunday.
Chiefs rookie linebacker Ramik Wilson seemed to make an early impression during rookie minicamp, especially on pass defense. Wilson had an interception during a live session Sunday and came back with two more interceptions Monday, according to the team's official website.
Bray (knee) returned to practice Wednesday, Adam Teicher of ESPN reports.
Bray has been sidelined for the beginning of the 2015 season due to an ACL injury suffered while playing basketball. There's no indication of when he may return, but it's also unlikely he'll have a roster spot even when healthy.
Jones (knee) is listed as questionable for Sunday's game in Tennessee.
Jones returned to a limited practice Friday, after missing practice both Wednesday and Thursday. He doesn't seem like a good bet to suit up, which may explain why the Raiders signed WR Jeremy Ross, who has extensive experience returning punts and kickoffs. An absence wouldn't have much impact on Oakland's offense, as Jones typically plays fewer than 15 snaps. However, Roy Helu would likely be active for the first time since Week 8.
