University of Southern California starting running back Marc Tyler pulled his right hamstring Tuesday on the first day of USC's spring practice and could be out for an extended period of time.
Tyler pulled up lame while running a pass route out to the north sideline on USC's Cromwell Field and was immediately treated by the Trojans training staff. He appeared to be in severe discomfort and sat out the rest of the session.
