Shockley, who had run the ball for a 9-yard gain the play before the turnover, pitched the ball to his right but it hit fullback Jeremy Thomas and the Gamecocks recovered the fumble.
"I really believe that he pitched it to the wrong guy," said Georgia coach Mark Richt.
"Out of his peripheral vision (Shockley) saw the fullback and he pitched it there instead of to the tailback and that drive hurt us. That drive and the next one killed some of our momentum," he said.
Georgia had a 10-0 lead at the 10:34 mark in the 2nd quarter, but did not score until near the end of the half. The play nearly resulted in a South Carolina score on the ensuing Gamecock possession, but their touchdown was negated due to a holding call.
"It was a bad pitch. The fullback was in good shape; there was plenty of separation between the fullback and the tailback and I think that the defensive end got on him in a hurry and he had to pitch it quickly. And I think that he pitched it to the first thing in his vision which was the fullback and it should have been the tailback," said Richt of the play.
"It was the only turnover this season. It was the only time that our offense has put the defense behind the 8-ball but our defense responded," he added.
Georgia still defeated the Gamecocks 31-7. The Dawgs moved to 2-0 (1-0) in the SEC while South Carolina dropped to 1-1 (0-1) and out of the AP rankings.
