Defensive end Ellis McCarthy, considered the jewel of UCLA’s freshman class, underwent surgery to repair a torn meniscus in his left knee.
McCarthy, ranked the No. 2 defensive tackle by Scout.com last year, will miss the first part of training camp.
UCLA also has had three players take medical retirements -- linebacker Mike Orloff (knee), safety Alex Mascarenas (concussion) and guard Wade Yandall (concussion).
