How is Harrison still in game for Steelers?

TAMPA, Fla. -- Officiating won't be the reason for defeat if the Cardinals lose this game, but we'll hear plenty about James Harrison's dirty tactics against Arizona's Aaron Francisco on that punt.

The officials obviously saw the infraction. They penalized Harrison on the play. How could an official see one player punch another player in the back, then deck that player, without ejecting him from the game?

Expect the Cardinals to ask that question following this game.
