Fearful his career could be in jeopardy, CC Sabathia had trouble sleeping as he awaited word if he needed microfacture surgery or a less serious arthroscopic procedure on his ailing right knee.

Sabathia will have season-ending arthroscopic surgery this Wednesday, but his doctors told him it should allow him to return for spring training.

"I was very concerned," said Sabathia, who turns 34 on Monday. "I told my wife last night, 'My season is over, but it was the first time was I able to get some real sleep,' just knowing that I don't have to have the microfracture and I can return next year."

Sabathia finished this season 3-4 with a 5.28 ERA. He has been plagued by a drastic loss in velocity on his fastball. On Wednesday, Los Angeles Dodgers team doctor Neal ElAttrache will perform the surgery.

Sabathia said he will have six to eight weeks of recovery time and then can begin to prepare for 2015. The procedure should clean up the debris in the knee, but it won't cure Sabathia forever.

"It is something I'm probably going to have to deal with the rest of my life and eventually have a big surgery," Sabathia said. "The goal is to keep playing and this is the easiest way to do it."

Yankees general manager Brian Cashman said Friday that Sabathia will still eventually need microfracture.
