Coach Mike Tomlin said today that quarterback Ben Roethlisberger has a shoulder sprain in his throwing arm that "puts his participation into the questionable category" for Sunday night's game against the Baltimore Ravens.
Tomlin said Roethlisberger's injury is a sprain to the sternoclavicular joint, which connects the breastbone to the collarbone.
Several other sources have told the Post-Gazette that Roethlisberger also sustained some form of rib injury when he was sacked by Chiefs linebacker Justin Houston.
The Steelers were hoping Pro Bowl safety Troy Polamalu might be able to return against the Ravens because he began working in individual drills last week. But Tomlin said Polamalu, who has missed the past five games with a torn right calf, is doubtful for the Ravens.
Tomlin also said safety Ryan Clark, who suffered a second concussion in three games, appears to be fine and could play against the Ravens.
Wide receiver Antonio Brown (ankle), who did not play against the Chiefs, is still rehabilitating his injury and is questionable to play against the Ravens. He also listed running back Rashard Mendenhall as questionable. Mendenhall has missed the past four games with an Achilles injury.
Roethlisberger did not return to the game and was taken to a local hospital for a magnetic resonance imaging exam.
He was replaced by Byron Leftwich, who completed 7 of 14 passes for 73 yards. If Leftwich starts against the Ravens, it will mark his first start since Sept. 27, 2009.
