Wright's shoulder injury was sustained while pinch running in last Sunday's game against the Dodgers, Evan Drellich of the Boston Herald reports.

EDGE Analysis

Wright entered the game as a pinch runner for David Ortiz, who had reached second base after a walk and a single. The pitcher jammed his shoulder while diving back to the bag after he'd taken a large enough lead to prompt a pick-off attempt. At this point, the disabled list is not in the discussion, but missing even one start from Wright is dangerous given the shaky nature of the Red Sox starting staff.
