SEATTLE (AP) - Yankees backup catcher Francisco Cervelli is out indefinitely with a concussion.
Cervelli was examined Monday in New York by Dr. Kirk Roberts, a neurologist specializing in concussion syndromes. The catcher was diagnosed with a concussion but MRI results were negative, the Yankees said.
Cervelli is resting at home and there is no immediate timetable for his return. All of his baseball-related activities have been suspended, the team said.
Banged up Thursday in a home-plate collision with Baltimore's Nick Markakis, Cervelli is batting .266 with four homers and 22 RBIs.
"My guess is we won't see him till we get home," Yankees manager Joe Girardi said.
New York is in the middle of a 10-game road trip and returns home next Monday.
With starting catcher Russell Martin still sidelined by a sore right thumb, the AL East leaders have been forced to hand the catching duties to a pair of rookies: Jesus Montero and Austin Romine.
Romine was just called up on Sunday.
"They might be called into duty if we do get to playoffs, bottom line," Girardi said. "We have to find out what they can do."
