Roethlisberger doesn't know if he can play Sun.

Pittsburgh Steelers' quarterback Ben Roethlisberger says he doesn't know if he can play against the Denver Broncos this Sunday or not.

Roethlisberger told a radio station in Pittsburgh Tuesday that he has an AC joint sprain and torn ligaments in his shoulder.

"I haven’t tried to throw a football since the game," Roethlisberger told Sportsradio 93.7. I’ll see the doctors and trainers tomorrow."

Roethlisberger was injured in the Steelers-Bengals game on Saturday when he was sacked in the 4th quarter by Vontaze Burfict. Roethlisberger left the game, but managed to come back in at the end and lead the Steelers on a game-winning drive.

Steelers' Coach Mike Tomlin said Tuesday that Roethlisberger has "a chance" of playing, but that Landry Jones will get the majority of the reps at quarterback early in the week.

Tomlin said wide receiver Antonio Brown will continue to go through the NFL's concussion protocol after taking a shot to the head from Burfict on Pittsburgh's final drive. The coach added that running back DeAngelo Williams and his injured right foot is "on the outside looking in."

The Steelers-Broncos game is Sunday at 2:40 p.m. MT.
