ATLANTA -- Mariano Rivera's rehab officially can begin.
The Yankees closer had surgery to repair the anterior cruciate ligament in his right knee Tuesday at the Hospital for Special Surgery in Manhattan. The procedure had been put off to wait for a blood clot in his right calf to clear.
"My surgery was a success, it went perfectly," a posting on Rivera's Twitter feed said late in the afternoon. "I am looking forward to beginning my rehab soon. Thanks as always for your prayers."
Initially, it was thought Rivera, 42, also suffered meniscus damage when he tore the ACL shagging flies during batting practice May 3 in Kansas City. The Yankees said "nothing was done to the meniscus, nothing's planned to be done with the meniscus."
"I think that's good news," Joe Girardi said. "I'm sure Mo's pretty anxious to get going. He was feeling pretty good walking around before the surgery."
Rivera has been at the Stadium a few times since getting hurt.
The day after the injury, Rivera declared his intention to return -- which he has repeated.
"It's another step to him coming back," Girardi said. "I think we're all expecting to see Mo pitch next year. I really don't think we're going to see anything this year."
