Here are the injuries we're monitoring from Sunday's Week 15 games:
- Ravens linebacker Matthew Judon exited with a knee injury against the Bucs and tight end Nick Boyle was ruled out with a concussion.
- San Francisco 49ers cornerback Ahkello Withersoon suffered a knee injury in the first half against the Seattle Seahawks and did not return. Coach Kyle Shanahan said afterward Witherspoon sprained his knee wouldn't rule out a torn ACL. Running back Matt Breida exited with an ankle injury on the game's last drive.
- Seahawks guard Jordan Simmons exited with a knee injury in the second half. Running back Rashaad Penny (knee) was inactive.
