Kamara (knee/ankle) is listed as a non-participant on Thursday's estimated injury report, Mike Triplett of NewOrleans.Football reports.

Kamara remains sidelined due to the sprained MCL that he suffered Week 12 against the Falcons, and if the Saints ultimately rule him out for Sunday's contest at Tennessee, he'll have just one more chance to suit up this season Week 18 in Atlanta. With Devin Neal (hamstring) on injured reserve, all of Taysom Hill (12), Audric Estime (five), Evan Hull (five), Tyler Shough (two and Mason Tipton (one) handled carries this past Sunday versus the Jets.

Montgomery (illness) is listed as active Thursday in Minnesota.

Montgomery missed Tuesday's walkthrough due to an illness and followed it up with a limited walkthrough Wednesday before the Lions listed him as questionable for Week 17 action. Mike Garafolo of NFL Network reported Thursday morning that Montgomery was expected to suit up, which now has come to pass. Working solidly behind No. 1 RB Jahmyr Gibbs over the last six games, Montgomery has reached double-digit touches only once during that stretch en route to 241 yards from scrimmage and three rushing TDs on 43 touches.

Williams suffered a shoulder injury during Thursday's game in Washington, Joe Hoyt of The Dallas Morning News reports.

After his four-yard touchdown run early in the second quarter, Williams didn't receive another touch before the Cowboys deemed him questionable to return. If he's unable to get back into the contest, he'll end Week 17 action with 13 carries for 54 yards and the aforementioned score and no catches (on two targets). Malik Davis should garner most of the RBs reps for as long as Williams is sidelined, but FB Hunter Luepke also is on hand for snaps.

Blue (coach's decision) is inactive for Thursday's game against Washington, Todd Archer of ESPN.com reports.

Blue has fallen out of the Cowboys' running back rotation, as he hasn't played since Week 8. Dallas will carry just two running backs -- Javonte Williams and Malik Davis -- plus fullback Hunter Luepke into their Christmas Day matchup.

Croskey-Merritt looks set to operate as Washington's lead backfield option Week 17 with Chris Rodriguez (illness) inactive for Thursday's contest against the Cowboys.

Croskey-Merritt will have a chance to operate in an expanded role in a favorable divisional matchup on Christmas Day, as he and Rodriguez have split backfield opportunities for Washington down the stretch of the regular season. With Rodriguez inactive due to an illness after having been added to the team's injury report Thursday morning, Croskey-Merritt could now handle a workload similar to what he saw Week 15 versus the Giants. Rodriguez couldn't face New York due to a groin injury, paving the way for Croskey-Merritt to log a career-high 18 carries for 96 yards and one score. Jeremy McNichols and Chase Edmonds are available as change-of-pace options behind Croskey-Merritt.

Rodriguez (illness) is inactive for Thursday's game against the Cowboys.

Rodriguez was added to the Commanders' injury report Thursday morning due to an illness, and now that he's been deemed inactive, look for Jacory Croskey-Merritt to lead a Week 17 backfield that also includes Jeremy McNichols and Chase Edmonds. Rodriguez thus will target a return to action in his team's season finale Week 18 against the Eagles.

Montgomery (illness), who is officially listed as questionable for Thursday's game against the Vikings, is expected to play, Mike Garafolo of NFL Network reports.

Montgomery was added to Detroit's injury report as a non-participant at Tuesday's walkthrough session and then managed to handle limited practice reps in Wednesday's walk-through, so it's always seemed as though he was trending in the right direction. While Montgomery's status won't be official until roughly 90 minutes prior to Thursday's 4:30 p.m. ET kickoff, the expectation is that he'll be able to play through his illness and handle his usual role as the top complementary option to Jahmyr Gibbs. Montgomery has now gone six straight games without recording double-digit carries, though he's scored in three of his last four appearances.

Rodriguez (illness) has been added to Washington's injury report and is officially questionable for Thursday's game against the Cowboys.

Rodriguez is a late addition to the Commanders' injury report and may simply have woken up ill Thursday morning. The third-year pro has logged four consecutive appearances with at least double-digit carries and scored twice in that span while working in a backfield split with Jacory Croskey-Merritt. As such, Croskey-Merritt would stand to benefit from an increased workload if Rodriguez can't go Thursday, while Jeremy McNichols and Chase Edmonds would be candidates to handle increased change-of-pace roles. Official word on Rodriguez's status will arrive no later than 90 minutes prior to Thursday's 1:00 p.m. ET kickoff.

Mostert (ankle) didn't participate in Las Vegas' practice Wednesday.

Mostert popped up on the injury report Wednesday after carrying the ball once for six yards and catching one pass for three yards during the Week 16 loss to the Texans. The 33-year-old's practice status throughout the rest of the week will provide more clarity toward his availability for Sunday's matchup versus the Giants. Dylan Laube would see increased playing time at both running back and kick return if Mostert ends up being unable to play.

Vidal (neck) didn't practice Wednesday.

Vidal also logged a DNP on Tuesday, so what the running back is able to do Thursday -- if anything -- will be pivotal in terms of his chances of playing Saturday against the Texans. If Vidal is unavailable this weekend, Omarion Hampton would figure to be busy against Houston, with fellow RBs Hassan Haskins and Jaret Patterson in reserve.
