TORONTO -- Francisco Cervelli isn't getting any better, opening the door for rookie catchers Jesus Montero and Austin Romine to both make the postseason roster.
Joe Girardi said before Friday night's game that Cervelli was still feeling the effects of a Sept. 8 collision at the plate with the Orioles' Nick Markakis in Baltimore.
"I got word today he's still experiencing concussion symptoms," Girardi said. "He's supposed to have some tests done early next week and then we'll re-evaluate."
Cervelli, sent home from the West Coast on Sunday, met with a neurologist Friday and will have another impact test Monday or Tuesday, the Yankees said.
The catcher, who has suffered three concussions in less than three years, is very much a question mark to be ready for the postseason, which Girardi for the first time acknowledged Friday.
"I think you have to prepare that he won't be [ready]," Girardi said. "Just because [a concussion] is so unpredictable."
If the rookies make the postseason roster, Montero likely would be used as a designated hitter with Romine serving as Russell Martin's backup.
