It's Week 16. A lot of teams face a do-or-die scenario this Sunday. Here are the injury stories we're tracking Sunday morning. We'll update right up until kickoff.
- ESPN's Chris Mortensen reports Green Bay Packers running Ryan Grant will start at running back against the Tennessee Titans. Alex Green (concussion) wasn't cleared to play.
- NFL.com's Ian Rapoport reports San Francisco 49ers defensive lineman Justin Smith (elbow) is "very doubtful" to play Sunday night against the Seattle Seahawks.
- Pittsburgh Steelers running back Rashard Mendenhall is slowly getting out of Mike Tomlin's doghouse. He will be active against the Cincinnati Bengals. Wide receiver Plaxico Burress is inactive.
- Washington Redskins quarterback Robert Griffin III (knee) was officially cleared by doctors Saturday. He will start against the Philadelphia Eagles.
- With no word from the NFL, it's safe to say Seahawks cornerback Richard Sherman will not begin serving any potential suspension this week.
- New England Patriots cornerback Aqib Talib is active against the Jacksonville Jaguars. He was a game-time decision. Tight end Rob Gronkowski (arm) did not make the trip.
- Carolina Panthers running back Jonathan Stewart is inactive against the Oakland Raiders. It's all on DeAngelo Williams.
- Eagles quarterback Michael Vick is inactive against the Redskins. He's now the team's No. 3 quarterback. Running back LeSean McCoy will start, though.
- Dallas Cowboys wide receiver Kevin Ogletree (illness) is active against the New Orleans Saints. He was listed as questionable.
- Miami Dolphins wide receiver Brian Hartline (back) is active against the Buffalo Bills.
- All three New York Jets quarterbacks are active against the San Diego Chargers. Tim Tebow and Mark Sanchez are behind Greg McElroy in line.
