CHICAGO -- Cubs relief pitcher Kerry Wood said he has a torn meniscus in his left knee and will miss the remainder of the season, and he said if the Cubs aren't interested in bringing him back next season he'll retire.

"I'm not going to play anywhere else," Wood said. "I'm hoping the Cubs want me back next season. My commitment is to the Cubs. And although I still want to pitch, if they don't want me back, then I'll retire."

The 34-year-old right-hander will have arthroscopic surgery after the season.
