Willson Contreras (hamstring) will play in a minor league rehab game for Double-A Portland on Friday.
Red Sox interim manager Chad Tracy told reporters Contreras will need at least one minor league contest to get back up to speed and could potentially return from the injured list as soon as Saturday’s game against the Royals. The 34-year-old first baseman hit the injured list with a left hamstring strain back on August 31.
