"Pittsburgh Steelers star safety Troy Polamalu was sidelined during the fourth quarter of Sunday's 17-13 win over the Jacksonville Jaguars due to concussion-like symptoms, according to coach Mike Tomlin.
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."
