The only thing Pittsburgh Steelers coach Mike Tomlin would say about quarterback Ben Roethlisberger's right, throwing, shoulder was that it was a sprain.
Going into Sunday's prime-time game with the Ravens, who they meet twice in the next three weeks, Tomlin said that "puts his participation into the questionable category" at a news conference Tuesday.
Byron Leftwich replaced him and is being made available to media leading into the Baltimore game -- not Roethlisberger.
Roethlisberger was injured when he was sacked by Kansas City Chiefs linebackers Justin Houston and Tamba Hali in the third quarter of a 16-13 overtime win Monday. Roethlisberger didn't return.
According to the Pittsburgh Post-Gazette, Roethlisberger also has a rib injury.
Tomlin also poured cold water on the chances of safety Troy Polamalu (calf) playing against the Ravens. Polamalu has missed the last five games and is doubtful, he said.
But safety Ryan Clark, who had a second concussion in three games against Kansas City and left in the fourth quarter, could play against the Ravens.
