Georgia now is dealing with injuries to both its star running backs.
Keith Marshall injured his right knee in the first quarter of the sixth-ranked Bulldogs' game with Tennessee on Saturday after getting hit by cornerback Cam Sutton while reaching for an incomplete pass.
Georgia officials announced Marshall wouldn't return to the game.
Georgia already was missing Todd Gurley, who sprained his left ankle last week. Gurley has rushed for 450 yards and four touchdowns on 71 carries.
After being helped off the field, Mashall lay on the sideline with his knee heavily wrapped as teammates consoled him. He later was carted into the locker room. Marshall had five carries for 33 yards before the injury.
Marshall entered Saturday with 213 yards on 51 carries.
