Polamalu was injured while making a hit on Jaguars running back Maurice Jones-Drew on a third-and-1 play. He left the game after that play, and spent the remainder of the game standing on the sideline with his helmet on. Tomlin updated Polamalu's status after the game.
"We erred on the side of caution there," Tomlin said. "We'll evaluate him to see where he is."
