McCarron was hit the same way shortly before that. And the CBS crew never really established whether the play was over when the Georgia QB was hit. The pass was intercepted, and then every Georgia player became a potential tackler. It was legal to block him, but the hit was too high.
Too high? Helmet to helmet hit on a player not even involved in the action of the return on the interception...the AL d-lineman will be suspended for the BCS Final.
