DETROIT -- Red Sox catcher David Ross has been diagnosed with a concussion and will be shut down from all physical activity for the next two weeks.
Ross visited with concussion specialist Dr. Michael Collins in Pittsburgh Thursday, who diagnosed the concussion. Ross suffered a concussion in mid-May and spent 12 days on the DL before returning.
This time, however, his absence will be longer. Ross won't do any baseball activity until he visits Collins again in the first week of July. He'll then need additional time before being cleared and returning to the lineup.
"Clearly, he's got a concussion,'' said John Farrell. "The results were evident in those tests. The recommendation by Dr. Collins was to basically shut down here. So he's going to be away from the team for a period of time.
"The thing we really have to be cautious with here, it's the second time he's suffered one and that will take some additional time to get over the symptoms. There's no timetable on his return; the only timetable we have is on that next appointment and where he'll be until then.''
Farrell said it was unclear what link there might be between the concussion he suffered in May and the current one.
"The fact is, he's got a concussion,'' said Farrell, "and because there's two in a short period of time here, we've got to be extra cautious. The one thing they do know is that staying in this environment is that staying in this environment (with the team) is that there's a lot of noise, a lot of intensity, travel...That's not the best situation to allow the current symptoms to subside.''
Ryan Lavarnway will be the backup for Jarrod Saltalamacchia and will likely get a chance to play against lefties, as Ross was.
"I think Salty's done an excellent job from the left side of the plate,'' said Farrell. "The defensive side of things have improved. I think we see [this] tandem working very similarly to one David had.''
