David Ross passes concussion test

Boston Red Sox catcher David Ross, who hasn't played since May 12, when he was struck in the mask twice by foul balls and sustained a concussion, has passed the ImPACT concussion testing, a necessary step to return to playing.

"The symptoms have resolved," Red Sox manager John Farrell said Monday. "He threw today, rode the bike for 30 minutes. There were no repeat of symptoms, so he's turned the corner. We look to increase the intensity to work tomorrow."

Ross is eligible to be activated and may be ready to play by Thursday, when the team returns to Boston. Farrell said the club has yet to decide whether Ross would benefit from a short rehab stint before being activated.
