Bryson DeChambeau tested positive for the COVID-19 virus and has withdrawn from the Tokyo Olympics Golf tournament.

DeChambeau said he was “disappointed” in not being able to compete in the Olympics.

“Representing my country means the world to me and it is was a tremendous honor to make this team,” said DeChambeau, who had finished fourth in the standings and ultimately replaced Dustin Johnson after he’d opted out.

“I wish Team USA the best of luck next week in Tokyo. I will now focus on getting healthy, and I look forward to returning to competition once I am cleared to do so.”

Patrick Reed will replace DeChambeau. It will be Reed’s second Olympic appearance after competing in the 2016 Games in Rio.

Reed joins Justin Thomas, Collin Morikawa and Xander Schauffele on the U.S. men’s team.
