CC Sabathia will have surgery to "cleanup" his troublesome right knee.

"It's not something that's of concern or considered serious," Brian Cashman said.

Cashman said team physician Dr. Christopher Ahmad will operate within the next week.

Sabathia, 36, pitched with a brace on the knee this year. He went 9-12 with a 3.91 ERA, his lowest ERA since 2012.
