Red Sox pitcher Clay Buchholz has a stress fracture in his lower back, according to a report on Comcast Sports New England. The right-hander was moved from the 15-day to the 60-day DL Sunday to make room for new acquisition Erik Bedard, and he will see a back specialist Monday in Los Angeles. If the move to the 60-day DL is dated from when he went on the DL June 19, he will have to miss at least a few more weeks. Buchholz has been suffering from what the team called a lower back strain.
