Glasnow didn't complete his scheduled simulated game Friday, Jack Harris of the Los Angeles Times reports.
Glasnow went straight to the clubhouse after warming up in the bullpen instead of facing hitters. It's unclear why he couldn't complete the session, but it doesn't bode well for his ability to return before the end of the regular season. Glasnow hasn't thrown for the Dodgers since Aug. 11 due to elbow tendinitis.
