Mitchell caught four passes for 31 yards and had one rush for -10 yards on Saturday. He also added 28 yards on two kickoff returns and one punt return.
Head coach Mark Richt did tell the Atlanta Journal-Constitution that Mitchell could return to the defensive side of the ball in the case of injury:
"He was our No. 2 nickelback behind (Damian Swann)," Richt said. "If anything had happened to Swannie he would have been in there."
Georgia now faces a huge matchup against South Carolina on Saturday, going on the road to Columbia to take on the No. 6 Gamecocks.
