Grove was removed from the Dodgers' NLDS roster Tuesday due to a shoulder injury, Bill Plunkett of The Orange County Register reports.
The details of Grove's injury remain unknown, though the issue is apparently severe enough to warrant holding him out for the remainder of the series. The 27-year-old righty would also be ineligible to pitch in the NLCS if Los Angeles advances past the Padres, meaning he will have to wait until the World Series before potentially making another appearance. In the meantime, Ben Casparius will act as Grove's roster replacement.
