The case of the pulled hamstrings

The Trojans are five practices into the spring and four of their players have already suffered hamstring injuries: tight end Randall Telfer, receiver George Farmer, running back Buck Allen and linebacker Dion Bailey.

What gives?

"I don’t know what to attribute that to except for just not much depth at the skill spots where it’s happening," coach Lane Kiffin said after Thursday's practice. "They’re taking a lot of reps. That’s the only thing I can guess."

The reps make some sense, but only for certain players. Telfer, the latest player to injure his hamstring when he came up lame Thursday, had been taking the vast majority of tight end snaps this spring while Xavier Grimble (toe), Junior Pomee (undisclosed) and Christian Thomas (hip) have been nursing injuries; Farmer was working as the No. 2 receiver because of Robert Woods' ankle injury.

Allen was getting carries as the third-string running back, but not a ton. And Bailey was playing his normal strongside linebacker snaps.

Telfer said he had "no idea" why so many players were getting hurt in the same manner, but he said his was a "freak accident" involving a cut in the wrong direction.

Farmer said he will not participate in Saturday's scrimmage. Kiffin indicated Thursday that Bailey may not be ready and Allen might not either. Telfer said he still anticipated being able to, but it seemed questionable with the way he walked off the practice field.
