Lions defensive end Ezekiel Ansah (shoulder) was limited in practice Thursday, per Kyle Meinke of MLive.com.
Ansah tallied two additional sacks in the Monday night loss at Seattle, pushing him to four on the season and into a tie for second in the NFL. While he's been listed with a different ailment each of the last three weeks, Ansah has brushed off the concern and played. So far, there has been no indication that the same won't occur in Week 5, but the Friday injury report should clarify his availability.
Bell (ankle) did not take part in Friday's practice, Dave Birkett of the Detroit Free Press reports.
Bell's Week 5 status will not officially be revealed until Friday afternoon, but it was reported Thursday that he is not expected to play this week, and a missed practice Friday certainly does not help his chances of suiting up Sunday.
Ebron (knee) did not practice Friday, but he was able to run on the side with trainers, Tim Twentyman of the Lions' website reports.
While Ebron was able to run around Friday, he did not log any practice participation this week and is almost certainly out for Sunday's game against the Cardinals. It was reported earlier in the week that he could miss up to three games, but with him already back up on his feet, he could have a chance to return to action after missing just one game.
Lions linebacker DeAndre Levy (hip) will make his season debut Sunday against the Cardinals, the Detroit Free Press reports.
Levy is ready to go after missing the first four games with the hip injury. He should give the unit a boost, and was one of the top Individual Defensive Player linebackers the last two seasons, so it's worth checking to see if he is available if you play in a Fantasy league that uses them.
Wednesday marks Pettigrew's first practice since sustaining the hamstring injury Sept. 13, and he could be ready for the Lions' Week 5 matchup against the Cardinals.
Fellow tight end Eric Ebron (knee) is also banged up and expected to sit out a couple weeks, which would likely promote Pettigrew to the starting spot for the time being. Tim Wright would also likely see more snaps in Ebron's absence.
Byrd will likely hop right in as a starter alongside Kenny Vaccaro, but the Saints may monitor the three-time Pro Bowler's snaps. Although his track record from Buffalo is superb, Byrd has played just 15 games since the start of 2013 and four games since the beginning of 2014. He needs to re-prove that he's a useful IDP outside of very deep leagues.
Saints wide receiver Marques Colston caught four passes on five targets for 19 yards in Sunday night's win against the Cowboys. Colston was not much of a factor in Week 4, with Drew Brees seemingly limited to short throws due to his injured shoulder.
Further, he once again lost playing time to second-year pro Willie Snead, who led the Saints with six catches for 89 yards, as Colston was on the field for only 41 of the Saints' 73 offensive plays (56 percent), according to the New Orleans Times-Picayune.
Brees still looks to Colston when he wants to move the sticks on third down, but with Colston essentially becoming a part-time player in New Orleans, his upside is limited. The Saints will face the Eagles in Week 5.
Cooks turned in a limited practice showing for a second consecutive Wednesday, but his ability to take part in all drills Thursday implies that he'll play Sunday at Philadelphia. Provided an exploitable matchup -- the Eagles have conceded 801 receiving yards and six touchdowns to wideouts in four games this season -- he'll strive for his first score of 2015 in Week 5.
Coming off a minor hip procedure at the beginning of September, Lewis is returning toward the front end of his timetable. He'll likely get the start, but it's not entirely clear whether he'll replace Brandon Browner or Delvin Breaux.
