Dodgers reliever Blake Treinen suffers a shoulder injury while warming up in the bullpen during the seventh inning of Los Angeles’ 4-3 win over the San Francisco Giants. Multiple outlets report he is likely to be unavailable for the postseason and is expected to be placed on the injured list.

The injury comes shortly after Treinen returns to action in early September following a prolonged absence due to right elbow inflammation, during which he missed 62 games. Reports describe the injury occurring before Treinen pitches in that game, with other bullpen options covering as the Dodgers manage the disruption. Some coverage characterizes the development as likely ending his season entirely or at least ruling him out for the playoffs; all accounts tie the setback to the shoulder injury sustained during bullpen warmups.
