When even the fittest and finest sports stars around the world are returning positive Covid-19 tests, it becomes clear that this virus does not discriminate. Luckily for some of the fittest people on the planet, the virus is unlikely to do any lasting damage to their physical health or their careers.
But the news can still cause temporary chaos across an entire sport, with plenty of examples of events and seasons being brought to a halt even since the restart of most activities in the summer.
Here are some of the more notable coronavirus cases to have hit sport recently...
Roberto Duran - The legendary 69-year-old boxer, whose most famous win came against Sugar Ray Leonard, was taken to hospital after testing positive for the virus in July but was thankfully later discharged.
Eddie & Barry Hearn - Eddie Hearn tested positive earlier this month and just two days later his father, while asymptomatic, also tested positive for the virus. Two weeks later, both are thought to have recovered.
Peter Fury - Savannah Marshall’s world title fight against fellow Brit Hannah Rankin billed for this Saturday was called off after her trainer, Peter Fury, tested positive. The fight will now be rescheduled for a later date.
Novak Djokovic - The world number one tested positive after taking part in an exhibition series he organised in Serbia and Croatia. Along with Djokovic’s wife, Fellow Serb Viktor Triocki and his wife, Grigor Dimitrov and his coach Christian Grob, and Croatian Borna Coric all caught Covid. Not Djok’s brightest idea.

Liverpool - New signing Thiago Alcantara tested positive on 29 September, and Sadio Mane also missed the 7-2 mauling by Aston Villa after contracting it. Lucky them.

Zlatan Ibrahimovic - Zlatan reacted to being hit by Coronavirus in the only way he knows how. "I tested negative to Covid yesterday and positive today. No symptoms whatsoever. Covid had the courage to challenge me. Bad idea," he wrote on social media in the most Zlatan way possible.

Rudy Gobert - Gobert was heavily criticised after he tested positive, just days after mocking the virus by touching every reporter’s microphone in a post-game press conference. He was the NBA’s first positive test.

The match was immediately abandoned and all those who had been in close contact with the player went into quarantine.
Giro d'Italia - Two teams have withdrawn from the ongoing Giro d’Italia, casting doubt over the viability of the entire race.
