Story (shoulder) will begin his rehab assignment with Triple-A Worcester on Sunday, Ian Browne of MLB.com reports.
Story will begin his assignment as the designated hitter before playing anywhere on the infield. The 31-year-old dislocated his left shoulder just eight games into the regular season, and the procedure to repair the injury was thought to be season-ending. However, Story has been ramping up his activity level following the All-Star break, and he will take the next step in his recovery Sunday. He will need several rehab games before being reinstated from the 60-day injured list, but a return to the majors before the end of the season is not off the table.
