What Ben Roethlisberger did Saturday was either downright stupid or the stuff of NFL legend. We'll find out which next weekend.

The Pittsburgh Steelers quarterback was carted off the field late in his team's 18-16 comeback victory against the Cincinnati Bengals on Wild Card Weekend, but later returned to lead the game-winning drive, which ended with a Chris Boswell go-ahead, 35-yard field goal.

Now, Roethlisberger's not saying what his injury is, but he isn't 100 percent healthy.

Though there is no official word on what the MRI revealed, the injury is believed to be a sprain of the AC joint in Roethlisberger's right shoulder, according to NFL Media's Albert Breer and Ian Rapoport.  The injury to his throwing arm is nothing to take lightly, but a sprain certainly is better than a broken collarbone.

If the damage wasn't severely worsened by Roethlisberger re-entering Saturday night's game -- or too severe in the first place -- Roethlisberger "will try to play Sunday" when his Steelers visit the Denver Broncos in the AFC Divisional Playoff, per NFL Media's Mike Silver.
