Former world number one Andy Murray has tested positive for coronavirus.
The 33-year-old Brit had been preparing for the year’s first Grand Slam, the Australian Open.
He was due to travel to Australia on one of the 18 charter flights laid on by tournament organisers but is still isolating at home.
Murray, who is said to be in good health, is hoping to be able to arrive in Australia at a later date and still participate in the tournament which begins on February 8.
Three-time Grand Slam winner Murray is a five-time finalist at the Melbourne event.
In the days before the 2019 competition, he cried at a news conference after saying he feared the tournament would be the last of his career as he struggled to recover from hip surgery.
The 33-year-old former Wimbledon champion has continued to try to get back to full fitness.
He made his grand slam return at the US Open and French Open last year but was knocked out in the early rounds and is currently 123rd in the world rankings.
Sir Andy joins a list of tennis stars who have had the virus, including Novak Djokovic and Grigor Dimitrov.
