Brooks, a junior, was the Tigers' leading returning rusher after tallying 246 yards and averaging 5.1 yards per carry last season. Clemson lost Roderick McDowell, the team's leading rusher in 2013, to graduation.
Clemson already had a lot of offense to replace before Brooks's injury, notably having lost quarterback Tajh Boyd and top two receivers Sammy Watkins and Martavis Bryant to the NFL draft.
The Tigers open the 2014 season Aug. 30 against Georgia.
