DENVER (AP) -- Dodgers ace Clayton Kershaw, sidelined since late June with a herniated disk in his back, was moved to the 60-day disabled list on Wednesday.
That means the 28-year-old won't be able to return until Aug. 27, at the earliest.
Los Angeles manager Dave Roberts said the three-time Cy Young winner hasn't participated in any baseball activity since he suffered a setback in a simulated game July 16.
"He has not thrown, he has not played catch, he has not picked up a baseball," Roberts said before the Dodgers faced the Colorado Rockies.
Roberts also said the team hasn't ruled out the possibility of season-ending surgery for Kershaw
Roberts made it clear, though, that nothing has been set in motion.
"I think that we're taking the approach that he is going to get back as soon as he can and when he can pick up a baseball," Roberts said. "But as you can see we've been reluctant from the beginning with Clayton as far as giving him a deadline or timetable."
Kershaw was 11-2 and touted a 1.79 ERA before the injury. The move on Wednesday corresponded with right-hander Louis Coleman (shoulder fatigue) and left-hander Adam Liberatore (elbow inflammation) being put on the 15-day DL.
The Dodgers have placed 25 different players on the disabled list year, a National League record.
"I'm very hesitant to say it can't get any worse," Roberts said.
