BERKELEY -- Cal sophomore cornerback Stefan McClure, who underwent surgery on his right knee Wednesday, will miss the remainder of the season, coach Sonny Dykes said.

"I hate it for him, personally. I know he's been through a lot to get back, and he worked incredibly hard," Dykes said after practice Thursday. "It's disappointing. He's a great kid, and he'll work through it. We hope to get him back for the second half of spring football."

Dykes said McClure, who was injured last Saturday against Washington State, did not sustain any ligament damage,

"It could have been a lot worse. It's not a nine-month injury," Dykes said. "He's disappointed he's not having a chance to play and contribute. Especially him ... it's been kind of a long journey. He'll be back."

This is McClure's second injury to the same knee since he arrived at Cal. He suffered a much more serious injury late in the 2011 season and sat out all of last season after undergoing two surgeries.

Cal also announced that starting linebacker Jalen Jefferson and reserve cornerback Joel Willis both will sit out Saturday night's game at No. 11 UCLA because of head injuries they incurred last week.

But junior linebacker Nick Forbes, who has missed virtually the entire season with back problems, is scheduled to play on the kickoff coverage team Saturday.
