Bears not sure yet who will start at QB

Colts’ QB Philip Rivers is retiring from football, he told @sdutKevinAcee.

Philip Rivers played 16 seasons for the Chargers and one with the Colts. He threw for at least 30 touchdowns six times in his career, and eclipsed 4,500 passing yards five times in that span. More impressively, Rivers didn't miss a single contest since becoming the Chargers' starting quarterback in 2006.

#Bucs WR Antonio Brown, who injured his knee and underwent an MRI following the game, did not suffer a serious injury, sources say. He’s considered day-to-day in preparation for the NFC Title Game vs the #Packers.

A clean MRI is good news for Antonio Brown's potential to play in the NFC Championship game this Sunday against the Packers. His practice schedule and availability is something to keep an eye on as the week progresses.

Patrick Mahomes is in the concussion protocol. "We'll follow that and see how he does the next couple of days," Andy Reid said.

If Patrick Mahomes doesn't clear protocol this week, Chad Henne would get the start for the Chiefs against Buffalo. Check for Mahomes' practice participation as the week progresses.
