The No. 5 USC Trojans will be without leading rusher Ronald Jones II for Saturday's game against the California Golden Bears due to a thigh injury.
Jones has been a key contributor to USC's 3-0 start, as he has registered 322 yards and five touchdowns on the ground to go along with three receptions for 85 yards and another score.
He was especially strong in a season-opening win over Western Michigan, racking up 159 rushing yards and three touchdowns on 18 carries.
While quarterback Sam Darnold entered the season with all eyes on him due to his Heisman Trophy candidacy, Jones has arguably been equally important to the Trojans' offensive success.
With Jones out of the lineup, there will be an even greater onus on Darnold and the passing game, while second-leading rusher Stephen Carr figures to get most of the carries out of the backfield.
