JACKSONVILLE, Fla. — Jacksonville Jaguars receiver Reggie Williams will have arthroscopic surgery after re-injuring his right knee during training camp.

Williams initially hurt his knee working out last week and opened camp on the physically unable to perform list. He was activated today and returned to practice, but tweaked his knee during the evening session. He made a spin move following a catch and then limped off the field. He was examined by team trainers and then carted to the locker room for tests.

Coach Jack Del Rio said Williams damaged cartilage in his knee. He expected the former first-round pick to make a full recovery, but declined to offer a timetable for his return.
