Ross to visit noted concussion specialist

BOSTON -- The Red Sox should get a better idea of how David Ross is responding to his second concussion of the season when the backup catcher goes to Pittsburgh to see Dr. Michael Collins on Thursday.

"I don't know if there's ever a normal recovery type or time with these -- they take on a life of their own," said Red Sox manager John Farrell. "After the foul ball Friday night down in Baltimore, there was further onset of symptoms. While he's not as severe as the first time he went on the DL, there's still some things that are lingering. We're going to send him out there to be examined."

Collins is the same noted concussion specialist that Boston shortstop Stephen Drew went to see during Spring Training.
