The Australian Open field has begun experiencing the effects of vaccination requirements and an international surge in coronavirus cases.
The biggest has been Rafael Nadal testing positive for coronavirus on his return from an exhibition in Abu Dhabi. The Spaniard is now in isolation for 10 days and was scheduled to arrive in Australia in nine days for some training before a warmup ATP 250 in Melbourne followed by the Australian Open.
Nadal, who was making his first on-court appearance since Washington, D.C., had also previously said he was still deciding if he would play the Australian Open as he returns from a foot injury.
On Tuesday, Olympic gold medalist Belinda Bencic and world No. 10 Ons Jabeur—who like Nadal each traveled back from the Mubadala Tennis Championship—revealed they also contracted COVID-19. Both commented on experiencing notable symptoms despite being fully vaccinated.
