The American golfer Bryson DeChambeau, the 2020 U.S. Open winner, has dropped out of the Olympics after testing positive for the coronavirus.
He will be replaced by Patrick Reed, the 2018 Masters winner.
DeChambeau tested positive as part of normal testing procedures for all athletes and others heading to Tokyo for the Games, U.S.A. Golf said.
“I will now focus on getting healthy, and I look forward to returning to competition once I am cleared to do so,” DeChambeau said in a statement.
The rest of the men’s team is Justin Thomas, Xander Schauffele and Collin Morikawa, the reigning British Open champion. The men’s tournament begins on Thursday.
Golf returned to the Olympics in 2016 after a more than 100-year absence. Justin Rose of Britain won the gold medal for the men and Inbee Park of South Korea for the women.
