Raburn (knee) showed little improvement Sunday and could be headed for an MRI if he doesn't make much progress in the next few days, MLB.com reports. "He won't do anything today other than get treatment, and then we'll kind of see how the next day or so goes. If he starts to improve, that's good. If he doesn't, then we'd probably think about getting him an MRI or something," manager Terry Francona said. There's a chance that Raburn's season will come to a premature end if he doesn't improve and the MRI shows anything more significant than the hyperextension. Consider him day-to-day for now.
