Tokyo: World number one Jon Rahm withdrew from the Olympics on Sunday after testing positive for Covid-19 for the second time in two months, the Spanish Olympic Committee confirmed.
Rahm, who stormed to victory at the US Open in June, returned a positive sample after undergoing mandatory testing following his recent participation in the British Open.
It was the latest twist to what has been a tumultuous season for the 26-year-old Spaniard.
In June, he was forced to withdraw from the PGA Tour's Memorial Tournament while defending a six-shot lead heading into the final round after returning a positive test.
Rahm later revealed he had been vaccinated shortly before contracting the disease.
He then bounced back from that setback to clinch a stunning victory at the US Open at Torrey Pines a fortnight later, taking the championship with back-to-back birdies on the final two holes.
