Yankees pitchers Bryan Mitchell and Adam Warren could be on deck if starter CC Sabathia lands on the disabled list.

Sabathia left Sunday's game with pain in his right knee and was taken for an MRI. He allowed four hits, two runs and walked four batters in 2 2/3 innings in a 4-3 loss to the Indians.

Yankees general manager Brian Cashman said he would talk with manager Joe Girardi about using Mitchell or Warren in a six-man rotation, but said the team could handle a five-man rotation in a worst-case scenario.

Cashman said Mitchell, who suffered a small nasal fracture after being struck in the face by a line drive last Monday, is going to start in a simulated game soon.

"One of the things I would kick around with Joe is do we want to stretch him out in the sim game because of what just happened today with CC?" Cashman said. "Initially we were going to try to limit it to 20 pitches or so, but now one of the things I'll talk to him about is, 'Do you want to consider stretching him out to 60 pitches because of what happened today?' "

Mitchell said the decision is out of his hands, but he threw 30-35 pitches in the bullpen Sunday and felt good. He is 0-1 with a 4.63 ERA in 11 2/3 innings in August.

"I feel pretty well conditioned," Mitchell said. "I could probably go out right now and throw 50 or 60, but that's not up to me. I'm just trying to get back to where I'm active. In my mind, I'd be ready for anything they want me to do."

Warren, a reliever, said he hadn't heard anything about his role in the immediate future. He said he would have to build up as a starter; something he figures could take three starts.

Warren said his biggest concern, however, is the health of Sabathia.

"Once he came out of the game, I said, something must be seriously wrong because he never comes out of games," Warren said. "He's a leader in this clubhouse, so it's tough to see a guy like him go down.

"Hopefully, it's not too serious and he can come back soon, but it worries me."
