The Indians announced on Tuesday that outfielder Grady Sizemore underwent a right knee arthroscopy on Monday in Colorado.
The recovery time for this procedure is 6 to 8 weeks. The 29-year old center fielder is expected to be ready for spring training 2012.
"We could not be happier with the results of Monday's arthroscopy," said Sizemore. "Dr. Steadman told me this minor procedure should allow the bone bruise in my right knee to fully heal."
