Much like the Broncos, the Steelers will enter the Divisional Playoffs with a host of injuries.

Pittsburgh’s injuries may be more alarming.

Receiver Antonio Brown suffered a concussion during the Steelers’ 18-16 win over the Bengals. Coach Mike Tomlin confirmed that Brown had a concussion after the game.

Brown appeared to be in good spirits after the game, but he will still enter the NFL’s concussion protocol, putting his status for Sunday’s game in doubt.

As Broncos team reporter Andrew Mason noted on Twitter, players have returned from a concussion within a week in the past, so Brown has a chance to play against the Broncos. In Week 15, Brown caught 16 passes for 189 yards and two scores against Denver.

Steelers quarterback Ben Roethlisberger also suffered a shoulder injury during the game. He returned to lead a game-winning drive, but was playing through pain.

KUSA-TV’s Mike Klis tweeted after the game that it “looks like Big Ben can’t raise right arm.”

“I’m going to give everything I can [to play Sunday,]” Roethlisberger said after the game, according to ESPN’s Jeremy Fowler.

Former NFL team physician David Chao tweeted that Roethlisberger “should play next week.” Chao called it “a classic AC joint sprain.”
