The Marlins left fielder will undergo right knee surgery Sept. 5 to repair his patellar tendon. Dr. Richard Steadman, one of the top knee specialists in the nation, will perform the surgery, which is the same procedure Morrison underwent last December.
Morrison's knee didn't successfully recover from that surgery, and it bothered him all season as he tried to play through the discomfort. He hit .230 with 11 home runs and 36 RBIs in 93 games this year before being placed on the 15-day disabled list July 29.
After meeting with Steadman in Vail, Colo., Morrison anticipated the need for a second surgery, but wanted to see how the knee responded to three weeks of rest. The Marlins moved him to the 60-day DL on Aug. 16.
Morrison said the expected recovery time from the surgery is up to six months, which would leave him ready for the start of Spring Training, barring any setbacks.
