Theo Epstein said Tuesday that Brandon Morrow had received an injection of Synvisc-One, a lubricant typically used to treat arthritic knees, in his ailing right elbow. That confirmed an earlier report by ESPN’s Jesse Rogers, who had talked to Morrow about his treatment protocol and timeline for return.
Morrow was shut down earlier in the month when he felt discomfort in the elbow following a mound session. He explained that the goal was to alleviate irritation near the surgical site and that the lubricant injection was meant to protect his elbow in the meantime.
