Raiders' Campbell to undergo surgery

Oakland Raiders quarterback Jason Campbell will undergo surgery on his broken collarbone and says he could be back before the end of the season.

Campbell said he will have the operation on Monday and that if everything goes right he could be back in six weeks.

Campbell got injured late in the first half of Oakland's 24-17 victory over the Cleveland Browns on Sunday when he landed hard on his shoulder at the end of a scramble.

He was replaced by Kyle Boller, who struggled in his first action of the season. The only other quarterback on Oakland's roster is rookie Terrelle Pryor, who was officially activated Monday after a five-game suspension and one-week roster exemption.

The Raiders are also looking at bringing in another proven quarterback.
