Byrd to undergo surgery

Outfielder's procedure will repair torn cartilage in left knee

ANAHEIM -- Rangers outfielder Marlon Byrd is planning to undergo arthroscopic surgery on his left knee later this week to repair torn cartilage that's causing a bone bruise.

The surgery will likely keep him from doing anything physical for about four weeks. By the first week in November, Byrd expects to begin his normal offseason workout regime.

"I'll be able to come in next year 100 percent, so it doesn't bother me," Byrd said.

Byrd began the season with a bad knee, and he ended up on the disabled list from April 17 to May 13. But it has never been at full strength, and it has only become progressively worse as the season went along.

"I probably came back too early," Byrd said. "But I didn't want to wait. I wanted to play, but I never gave it a chance to heal. It's painful, but I think it's mental. I can handle a lot of pain, just go out, play hard and block it out. It doesn't bother me when I run hard. Slowing down is when I feel it."
