David Ross placed on 7-day disabled list with concussion, Ryan Lavarnway called up

The Red Sox have placed catcher David Ross on the seven-day disabled list with a concussion, calling up Ryan Lavarnway to take his place.

It's not hard to figure out how Ross ended up hurt. During Saturday's loss to the Blue Jays, the veteran catcher took a pair of sharp foul balls off his mask. Ross would stay in the game, but it's no surprise to learn that they more than rattled him.

It's just more bad news for a Red Sox team that doesn't need to be losing pieces right now. David Ross had been seeing more and more action, starting just about every other day with some consistency, taking playing time away from the very hit-and-miss Jarrod Saltalamacchia.

Now instead of a top defensive backup, the Red Sox will have to rely on Ryan Lavarnway, who has never really shown he can play well behind the plate. It's a chance for Lavarnway to prove himself after a dismal 2012 performance, but this isn't a time when the Red Sox want to be taking chances on minor leaguers who have struggled in the majors.
