Georgia running back Keith Marshall started on Saturday against Tennessee in place of Todd Gurley but left the game after being hit on his right leg.
Marshall went out into the flat for a pass and was tackled by Cam Sutton. The impact was to his right knee, which looked to have bent awkwardly. After being checked out by Georgia trainers, Marshall was carted to the locker room with ice wrapped around his knee and a distraught look on his face while accompanied by his father, Warren.
Gurley was dressed in street clothes for Saturday's game after rolling his ankle against LSU. Before leaving the LSU game, Gurley had 73 yards on just eight carries. He attempted to practice before the Tennesee game, but wasn't able to be ready for the game.
The tandem dubbed "Gurshall" have been the workhorses for the Georgia running game since the beginning of last season. After combining for over 2,000 yards last year, Gurley has 450 yards this season while Marshall entered the Tennessee game with 213 and had 33 yards before he was injured.
J.J. Green, who had five carries in Georgia's first four games, replaced Marshall as the team's primary ballcarrier.
