The NFL playoff race is ramping up, and injuries play a major factor. While some teams' injured players try to get back on the field, others have gone down.
Here's a look at injuries to prominent players heading into Week 14.

Ingram sat out Wednesday's practice with a toe injury and is a game-time decision for Thursday night's game against Atlanta. Alvin Kamara would see more snaps if Ingram is unable to go, though Ingram is expected to play.

Matthews has been ruled out for the season with a knee injury. The Bills could get some relief, however, as Kelvin Benjamin (knee) has returned to practice this week.

McPhee left Sunday's game with a shoulder injury and sat out Wednesday's practice. His status for this week's game is unclear.

Mixon is in the concussion protocol after Monday night's brutal game against the Steelers. He could have a tough time playing on a short week.
14 of 21
Alec Ogletree, LB, Rams

Ogletree injured his elbow on Sunday, but the Rams still expect him back in a huge home game against the Eagles this week.
Jake Roth / USA Today Sports Images
Peppers sat out Wednesday's practice after leaving the last game with a knee injury. Cleveland has confirmed the rookie will be back this season, but a return this week against Green Bay is in question.
16 of 21
John Ross, WR, Bengals
Brian Spurlock / USA Today Sports Images
The speedy Ross has been ruled out for the season with a shoulder injury that will require surgery. His rookie season has been a lost year due to injuries and ineffective play.
17 of 21
Ryan Shazier, LB, Steelers
Aaron Doster / USA Today Sports Images
Shazier was moved to a Pittsburgh hospital after leaving on a stretcher due to a scary hit on Monday night. He's been diagnosed with a spinal contusion and is out indefinitely.
18 of 21
Matthew Stafford, QB, Lions
Tommy Gilligan / USA Today Sports Images
Stafford got in a limited practice on Wednesday due to a bruised hand. He's questionable for this week's game but will more than likely play with the Lions fighting for a Wild Card spot.
19 of 21
Cordrea Tankersley, CB, Dolphins
Steve Mitchell / USA Today Sports Images
Tankersley got banged up with shoulder and ankle injures on Sunday, but the team expects him to practice later this week. He has an extra day to rest with the Dolphins playing New England on Monday night.
20 of 21
Tyrod Taylor, QB, Bills
Timothy T. Ludgwig / USA Today Sports Images
Taylor didn't practice on Wednesday due to a patellar tendon contusion but did return Thursday. It's unclear if the Bills will go with Nathan Peterman or Joe Webb at quarterback if Taylor is unavailable this week.
21 of 21
Tre'Davious White, CB, Bills
Timothy T. Ludgwig / USA Today Sports Images
White was limited in practice on Wednesday due to a concussion after Rob Gronkowski took a dirty shot on him that resulted in a one-game suspension. His status for this week is unclear.
