Gresham out after knee surgery

NORMAN, Okla. -- Oklahoma tight end Jermaine Gresham will miss the rest of the season after having surgery to repair torn cartilage in his right knee.

Coach Bob Stoops said that doctors determined during an arthroscopic surgery Tuesday that they needed to stitch together the cartilage in Gresham's knee. Stoops said Gresham will need five months to recover.

The 13th-ranked Sooners are already reeling from the loss of Heisman Trophy-winning quarterback Sam Bradford, who sprained his shoulder in a 14-13 loss to BYU and will be out at least two weeks.

Gresham was a second-team All-America pick last season and had been considered a top NFL prospect before returning for his junior year.

Gresham was Oklahoma's top returning receiver with 66 catches for 950 yards and 14 touchdowns last season. He needed only five more TDs to tie the school's career record of 31 set by Mark Clayton. Now, he's another key cog missing from what was the highest-scoring offense in college football history last year.

"He's such a main target, presence on the field and quality player that it changes," Stoops said. "It changes everything, your run-blocking along with your protection, along with him out in routes and, in particular, red zone stuff. You just have to work through it."
