Pittsburgh Steelers coach Mike Tomlin indicated that star safety S Troy Polamalu could possibly return Sunday against the Baltimore Ravens, depending on the results of his magnetic resonance imaging exam conducted Tuesday. Polamalu has missed the past five games with a knee injury. He has played in just five games this season. "The result of his MRI is going to dictate what direction we take, like it has in recent weeks," Tomlin said. Source: National Football Post
