Kyle Wilber breaks thumb, needs surgery

ALAMEDA, Calif. -- Kyle Wilber will likely need surgery to repair a broken left thumb and keep the rookie outside linebacker out for at least four weeks, according to Cowboys owner and general manager Jerry Jones.

Wilber will fly back to Dallas for the surgery, but he was unsure when.

“It’s really disappointing,” said Wilber, who was unsure when he suffered the injury. “It’s kind of a setback, now I’ve got to wait until I get back.”

Wilber missed most of the offseason with a fractured right index finger that required surgery. He returned for the three-day rookie camp at Valley Ranch late last month and had not missed a practice in training camp. He was credited with a quarterback hurry in the first half of Monday’s 3-0 win against Oakland.

“I want to only get better and still prove I’m a good player,” Wilber said, “but I can’t do it.”

Jones said there were no other injuries of note. Tight end Jason Witten missed a few snaps after taking a hit from Raiders linebacker Rolando McClain. Witten said he just had the wind knocked out of him. He returned and finished with two catches for six yards.
