Dolphins C Mike Pouncey was carted off the field with a foot injury in the first quarter of Sunday's Week 12 game.
He looks doubtful to return. The Dolphins are also missing RT Ja'Wuan James on the offensive line.
Cardinals GM Steve Keim told FOX Sports' Jay Glazer re-signing CB Tyrann Mathieu is one their "biggest priorities."
Mathieu has another year left on his rookie deal, but locking the playmaker up to a long-term extension before he can hit free agency makes sense for Arizona. Mathieu has 57 tackles, a sack and three interceptions through ten games this season.
Rishard Matthews left Sunday's Week 12 game against the Jets with chest and ribs injuries.
Matthews walked off the field gingerly and is questionable to return.
Derek Carrier exited Week 12 against the Giants with an ankle injury.
Carrier limped off after making a catch on the Redskins' first drive. He is questionable to return.
Bengals declared WR Mario Alford, OLB P.J. Dawson, DT Marcus Hardison, DE Margus Hunt, OT Cedric Ogbuehi, DT Pat Sims and TE C.J. Uzomah inactive for Week 12 against the Rams.
Alford hasn't seen the field yet this season. Vontaze Burfict (knee), Andy Dalton (groin), Pacman Jones (foot), Marvin Jones (hamstring), Dre Kirkpatrick (knee) and Andre Smith (thigh) are all active.
Rams declared QB Case Keenum, OT Isaiah Battle, OT Andrew Donnal, CB Trumaine Johnson, DE Robert Quinn, DT Ethan Westbrooks and K Greg Zuerlein inactive for Week 12 against the Bengals.
Keenum practiced on a limited basis this week but still needs to pass the league's concussion protocol. Nick Foles will fill in at quarterback. The Rams will also be without Greg Zuerlein (groin). Rob Havenstein (calf) is active for St. Louis.
Jets declared CB Darrelle Revis, QB Bryce Petty, WR Kenbrell Thompkins, S Dion Bailey, OL Dakota Dozier, OL Ben Ijalana, and LB Josh Martin inactive for Week 12 against the Dolphins.
The Jets will start Marcus Williams at cornerback opposite Antonio Cromartie.
Bills declared RG John Miller, QB Josh Johnson, OT Cyrus Kouandjio, OG Ryan Groy, WR Marcus Easley, DE Mario Williams, and DT Kyle Williams inactive for Week 12 against the Chiefs.
Miller sprained his ankle last Monday night. Easley suffered a concussion, and Mario Williams hurt his foot in the same game. Kyle WIlliams is done for the year.
