Carl Crawford recently returned to Boston to have his left elbow examined by team doctors, who diagnosed him with a minor strain. Crawford, who is currently on the disabled list since while he continues to rehab from wrist surgery in January, said he suffered the recent elbow strain while throwing. "I'm just waiting to get back on the field," Crawford said. "I had to come up here to get my elbow checked and I think it was best to be here with the doctors for the next few days. I'm not sure when I'm going back to Fort Myers, but I should be heading back pretty soon."
