Penalty flag on the miracle play

I was at the game, and with so much noise I never really heard the call on the flag, except I thought he said the penalty would be enforced on the kickoff.

On the CBS replay, Wagers calls unsportsmanlike conduct on number 90 for Auburn, which would be Gabe Wright. I looked at the UGA roster and their only #90 is a punter. Did Gabe come off the sidelines celebrating? And if so, where was the infraction marked off? Parkey kicked from the 35 like normal on the kickoff.
