An injury will keep Matthew Centrowitz from competing in his fourth Olympic trials, and seemingly bring to a close a long and decorated career for the U.S. track star.

Centrowitz posted to X on Friday that a hamstring injury has forced him to scratch out of the men’s 1,500 meters, which begins Friday as the U.S. Olympic trials for track and field open at Hayward Field in Eugene.

“Unfortunately, I won’t be having the fairy-tale ending I was hoping to have this week at my fourth Olympic trials,” the former Oregon Ducks star posted.

Centrowitz, 34, previously had said that the 2024 season would be his final one competing professionally on the track.

A five-time national champion in the 1,500, Centrowitz won Olympic gold in the event at the 2016 Rio de Janeiro Games. It was the United States’ first gold in the men’s 1,500 since Mel Sheppard in 1908.

Centrowitz also took silver in the 1,500 at the 2013 world championships and bronze in the event at the 2011 world championships. He won gold at the indoor world championships in Portland in 2016 and was the outdoor 1,500 NCAA champion in 2011.

“I still traveled to Eugene to hang out and celebrate with family & friends who came to watch me race,” Centrowitz posted Friday. “So if you see me around Eugene the next few days, don’t be bashful.

“It’s not goodbye. It’s see ya later …”
