Muncy (oblique) will begin a rehab assignment at Triple-A Oklahoma City over the weekend, Bill Plunkett of The Orange County Register reports.
Muncy will spend at least a week in Triple-A before returning to the Dodgers, putting his earliest possible return date sometime in mid-August. The slugging third baseman has been on the injured list since May 17 with a right oblique strain and only recently began making strides in his recovery after a chiropractor visit last week.
