"2006 SEASON
Came to Columbia during the summer to get a jump on his acclimation period, and by all accounts was on his way to likely earning playing time as a true freshman, before a knee injury suffered in 7-on-7 passing drills in July sidelined him for the year ... Showed a very determined work ethic during the rehab process, and was cleared to practice with the team before the end of the season."
I guess he was injured that 1st season, but it still counts toward him being out of high school for the three years necessary to enter the NFL.
