This just in from Clemson's sports information department:
Starting offensive guard Barry Humphries had knee surgery on Tuesday in Seneca, S.C. Dr. Larry Bowman, the Clemson team orthopedic surgeon, performed the operation. After the surgery it was determined that Humphries will miss four to six weeks. He will be re-evaluated at that time. Clemson redshirt freshman Mason Cloy has moved into the starting lineup in his place.
