The school announced Brooks' injury Wednesday. Football spokesman Tim Bourret said Brooks will need surgery but per Clemson policy did not provide specific details on the injury.
Brooks was the 16th-ranked Tigers' top returning running back after playing behind 1,000-yard rusher Rod McDowell last season. Brooks rushed 48 times for 246 yards.
Clemson coach Dabo Swinney says the 6-foot, 200-pound back will rehab the injury this season and return next fall as a redshirt junior.
Brooks has played in 18 games the previous two years, rushing for 365 career yards. He has also caught nine passes for 92 yards and a touchdown.
