The extent of Sizemore's injury, and how long he'll need to recuperate, won't be known until Dr. Richard Steadman begins the procedure.
DETROIT, Mich. -- Indians center fielder Grady Sizemore will undergo surgery Friday on his left knee. The surgery, which could end Sizemore's season, will be performed by Dr. Richard Steadman in Vail, Colo.
Sizemore bruised his knee sliding into a base in April. He re-injured the knee diving back into first base against Baltimore on May 16 and was placed on the disabled list. Lonnie Soloff, Indians head athletic trainer, said he'll miss at least six to eight weeks.
"I hope and pray that when Steadman goes in it's not so bad and he can do the simplest procedure," said manager Manny Acta, "and have the kid back as soon as possible healthy for his own good. Then he can play for us whenever he's ready."
Soloff said the Indians won't know the extent of Sizemore's injury until Steadman begins the procedure. He said he should have an update on Sizemore's condition by Friday or Saturday.
Sizemore was the Indians version of the Iron Horse through his first four years. Last season he played in 105 games and missed most of September due to surgery on his left elbow and left groin.
