Dodgers reliever Tom Koehler, who has been sidelined all season by a right-shoulder strain, suffered a setback in his rehabilitation last week and has been shut down, manager Dave Roberts said.
Koehler, who was expected to replace Brandon Morrow as the team’s primary setup man, was hoping to return around the All-Star break. Roberts said that timetable has now been pushed back to “sometime in August.” The Dodgers believe Koehler will be able to resume playing catch later this week.
Left-hander Hyun-Jin Ryu, sidelined since May 3 because of a left-groin strain, also suffered a minor setback on Saturday when trainers stopped his bullpen session after 20 pitches because of a little tightness in his groin.
