LOS ANGELES -- When USC ended spring practice, depth at tailback was issue No. 1. They had just three scholarship tailbacks.
Fast forward to the Wednesday before No. 2 USC (1-0) is set to take on Syracuse (0-1) in their second game of the season, and the Trojans are once again down to three scholarship tailbacks for the foreseeable future.
Running back D.J. Morgan announced via Twitter that he would be undergoing "minor" knee surgery on Wednesday and will miss 3-4 weeks.
It was not announced by the school because of USC's new policy to not discuss injuries but after practice USC head coach Lane Kiffin confirmed the tweet.
"That's true," Kiffin said.
It is unknown which knee Morgan will have surgery on. During his senior year at Taft High School, Morgan tore the ACL in his right knee and partially tore his meniscus, which led to him redshirting in 2010 as a freshman with the Trojans.
He began 2011 as the starting tailback before ball security issues caused him to lose his job.
