Tokyo Olympics: World No.1 golfer John Rahm tests positive for COVID-19, out of Games

World No.1 golfer Jon Rahm has tested positive for COVID-19 and has been ruled out of the Tokyo Olympics.

This is the second time in two months - and third overall - that Rahm has tested positive, after being forced to withdraw in June from the Memorial Tournament in Ohio, as he was leading by six strokes.

The Spaniard tested positive in the final testing protocol before leaving for the Olympics, the International Golf Federation says.

The Spanish Olympic Committee says, due to time constraints, a replacement will not be provided and only Adri Arnaus will represent the country in the men's competition.

Since returning from his Ohio test, Rahm has been in sensational form, taking out the US Open and charging hard over the final round at this month's British Open Championship, finishing tied for third.

His performance at Royal St George elevated him to the top spot on world rankings.

Earlier, US golf star Bryson DeChambeau announced he had also tested positive for COVID and was replaced in the American Olympic team by 2018 Masters champion Patrick Reed.
