Hall tore the ACL in his left knee last Thursday, landing awkwardly after intercepting a pass to end the first players' only workout. While Hall was able to walk off Howard Jones Field, he knew the injury was serious.
"I was able to walk off the last ACL tear I had and I knew it was the same thing (this time)," Hall said. "I just didn't want to show everybody."
Hall will undergo surgery in the next few weeks once the swelling in his knee subsides, then faces a nine-month recovery.
"I already talked to the trainers and they said hopefully I can be jogging in about three months," Hall said.
This is the second major knee injury Hall has suffered while in college. He tore his right ACL during his only practice of fall camp in 2009 with the Trojans while awaiting a ruling on his eligibility.
After finally enrolling in January 2010, Hall redshirted last season as he continued to rehabilitate the injury.
Hall was suspended indefinitely in the fall by coach Lane Kiffin for violations of team rules, but was later reinstated.
A limited participant during spring practice, Hall looked to have regained the athleticism that made him a touted recruit at Ventura (Calif.) St. Bonaventure.
Because he will have missed two seasons due to injury, Hall can petition the NCAA for a sixth year of eligibility. Hall said he has spoken with graduate assistant Sammy Knight about that possibility and plans to do so to pursue a Master's degree.
