Pittsburgh ? The Pittsburgh Steelers have no knowledge that Ben Roethlisberger played the Super Bowl with two broken ribs, as the quarterback told a Web site.

According to SI.com, Roethlisberger said his fractured ribs did not show up on X-rays taken before he led the Steelers to a 27-23 victory over Arizona on Feb. 1, but were revealed only during a MRI test he had last week.

“Luckily, in the game, I didn’t take any big hits to make ’em hurt,” Roethlisberger told SI.com. “But I knew all along there was something wrong. There wouldn’t have been anything that could have been done about fractured ribs anyway. It was just suck it up and play.

Roethlisberger did not miss any practices before the Super Bowl, although a pool report from the Wednesday practice said he attempted during the middle of the workout to stretch his torso. He missed one practice during the off week before the Super Bowl because of what the team said was a back injury.

In the Super Bowl, Roethlisberger led a 78-yard drive that ended with a precisely thrown six-yard touchdown pass to Santonio Holmes with 35 seconds left.
