"We would hope that at that point there would be clearance to put a ball back in his hands," Boston manager John Farrell said before Sunday's series finale against the Tigers. "This isn't a result of any plateauing. He feels good physically, the strengthening and all the exercise he's gone through as anticipated. This is more clearance to begin a throwing program."
