Strong safety Troy Polamalu has a sprained MCL in his left knee and though it's too early to tell, head coach Mike Tomlin classified it as a three-to-six week injury.
That's not good news for the Steelers defense, which will play its next two games on the road at Chicago and and Cincinnati before coming home to host San Diego.
Even at the minimum of three weeks, those are three opponents who will be a stiff test for Pittsburgh's pass defense.
And Tyrone Carter is in no way, shape or form as good as Polamalu.
© Polamalu's leaping, one-handed interception in the first half of this game was one of the top five defensive plays I've seen in person in any sport.
Polamalu also has at least one of the others - his diving finger-tip interception last season being the other.
© The national media at this game were raving about Ben Roethlisberger's comeback and improv skills. Welcome to the party, boys.
Roethlisberger was 18 of 22 passing in the second half and overtime and three of those incompletions came on the game-winning drive.
© With Polamalu out, it becomes very important that Lawrence Timmons, who sat out this game with an ankle injury, be back in time to play against Chicago next week.
Keyaron Fox played well in Timmons' spot, but Timmons' speed in the passing game will be needed against the Bears.
© Though it wasn't on the same stage, Hines Ward almost pulled a Jerome Bettis with his fumble at the end of regulation.
Roethlisberger saved Bettis on that occasion as well.
© After a slow start, I thought the offensive line played better as the game wore on.
I'm still not sure why right tackle Willie Colon didn't pick up Jevon Kearse on Tennessee's lone sack of the second half, though.
What'd he think, Kearse was going to drop into coverage?
Colon let him go unblocked, turning to pick up the inside guy.
© Was punter Craig Hentrich thinking just a little bit about kicking the ball to Stefan Logan when he shanked a 28-yard punt late in the game? Just asking.
