It looks like Steelers safety Troy Polamalu had a concussion in Pittsburgh's 17-13 win against the Jaguars on Sunday. After the jump is video of the play that appears to have done it. Polamalu sneaks through Jacksonville's line untouched and tackles Maurice Jones-Drew at the line of scrimmage. Polamalu throws his head at Jones-Drew, and it looks like his head might have hit Jones-Drew's knee. (Also, Ryan Clark headbuts Polamalu in celebration after the play, but in the absence of evidence to the contrary, I'm going to guess it was the tackle that did it. The headbut is pretty mild. Brett Keisel runs into Polamalu on the play, too, but it doesn't look like he hits Polamalu in the head.)
It was a fantastic play by Polamalu; let's hope it doesn't keep him off the field. Head injuries have been the story in Pittsburgh sports over the past year, and it would be a shame if the storyline continued. Sidney Crosby appears to be about to come back for the Pens, so let's hope Polamalu's concussion does turn out to be mild (which is how it's been reported) and he's back soon.
It's unclear whether Polamalu will play next week. We should know more on Tuesday.
