Cervelli traveled with the Yankees to Tropicana Field and resumed baseball workouts, trying to return from a Sept. 8 concussion sustained in Baltimore, but he did not come out of the session cleanly.
"He threw and did some catching stuff, and some of the symptoms came back," Yankees manager Joe Girardi said.
Girardi said that head athletic trainer Gene Monahan would speak with the neurologist treating Cervelli to determine a next step of treatment.
"The health is always the biggest issue, more than any postseason," Girardi said. "We've got to get this kid healthy."
Cervelli has had at least three known concussions in his career, including the most recent one on a home-plate collision with the Orioles' Nick Markakis.
Girardi has already stated that he expects both Jesus Montero and Jorge Posada to be on his postseason roster, and that Russell Martin will start every game at catcher if healthy.
