Steelers QB Ben Roethlisberger has a sprained left foot, sources told ESPN'S Chris Mortensen. It is unknown if the injury will prevent Roethlisberger from playing in the team's Week Five game against the Titans. A scan performed on the foot was negative for a fracture, the sources told Mortensen, an MRI was inconclusive because of swelling in the foot. Roethlisberger was injured in the fourth quarter of Pittsburgh's Week Four loss to the Texans after being tackled from behind by a defender. He was X-rayed after the game and left the stadium in a walking boot, when asked about it, the quarterback said he wasn't even concerned with the Tennessee game yet. "I don't know. I'm still worrying about this game," Roethlisberger said. "It's still too fresh in my mind to worry about next week yet. You know me — if I can be out there, I'm going to be out there. That's so for next week, too." Source: ProFootballWeekly
