Stone still has pain in his shoulder and has not been able to start a throwing program since going on the injured list after his Aug. 31 start in Arizona.

Stone, 25, has not appeared in a game since August 31. In 25 starts prior to his deactivation, he amassed a 3.53 ERA (111 ERA+) and a 3.14 strikeout-to-walk ratio. His contributions have been worth an estimated 1.8 Wins Above Replacement, according to Baseball Reference's calculations.

Although it had been expected Stone wouldn't pitch again this season, the news throws the Dodgers' postseason rotation into further flux.
