First it was the jock itch. Then USC tailback Joe McKnight injured his fingers by slamming them in a doorway in an incident the Trojan coaching staff SWEARS wasn’t horseplay.
Now, McKnight has a hyperextended elbow. McKnight suffered the injury during a scrimmage at the Coliseum on Saturday. He was in an arm brace Sunday and is expected to miss several more days of practice.
McKnight, who was one of USC’s most highly recruited running back prospects in years, is one of six highly talented players scrambling for carries in the crowded USC backfield. McKnight averaged 5.7 yards per carry last season but has yet to break through as a number one back for the Trojans.
