Family issues have led to Broderick Green telling coaches he intends to transfer.
Green told Trojan coaches of his plans late this past week.
Green's appeared in six games this season, carrying the ball 32 times for 168 yards and three touchdowns.
Green, a former four-star recruit from the Pulaski Academy in Little Rock, Ark., chose USC over Ohio State, Penn State, Arkansas and Tulsa.
After having a breakout game by rushing for two touchdowns and 121 yards on 18 carries during the Trojans' 69-0 win at Washington State, Green did not carry the ball against Arizona and rushed just five times in USC's 56-0 win over Washington.
Green did not dress against Cal Saturday.
With Marc Tyler returning from a quad injury, Green appears to be fifth on the Trojans' depth chart, behind C.J. Gable, Stafon Johnson, Joe McKnight and Tyler.
Each of those backs should return next season, in addition to Allen Bradford, who is sitting out the season after hip surgery, and Curtis McNeal, a freshman who is likely redshirting.
In addition to all returning, only Johnson would be in his senior season if Bradford receives a medical redshirt.
