The Yankees say Cervelli needs surgery and will miss a minimum of six weeks. Nova left his outing against the Blue Jays on Friday night after allowing a single to the second batter of the third inning. He will have an MRI later Friday.
After allowing a ground single up the middle to Rajah Davis, trainer Steve Donohue and manager Joe Girardi immediately ran out to the mound, and Nova walked off without hesitation.
Nova gave up two runs and four hits in two-plus innings.
