Titans Coach Jeff Fisher said the Steelers got away with at least a couple of penalties on Sunday.
Steelers linebacker James Harrison should have been flagged for body-slamming quarterback Vince Young in the third quarter, according to Fisher.
"You say if that happened to (Tom) Brady or that happened to so-and-so or so-and-so there would have been seven flags on the field," Fisher said. "Why wasn't there one yesterday? I don't know. Maybe it was the heat."
Fisher also said that Steelers safety Troy Polamalu should have been penalized near the end of the game when he jumped over offensive linemen to tackle quarterback Kerry Collins for a 1-yard loss.
