Impact: The team says Griffey had the surgery on Monday in Cincinnati and was performed by Dr. Timothy Kremchek. Normal recovery time is four to six weeks. It's the second time in a year that Griffey has undergone surgery on his left knee. He was limited by the knee at times during the 2009 season. He had it drained on multiple occasions. Griffey, who turns 40 in November, has not announced whether he will play in 2010.
