The sight of some of the world's biggest tennis stars touching down for the upcoming Australian Open tournament has frustrated many Australians unable to return home due to the pandemic.
British media reported that Murray was in good health and still hoped to compete at Melbourne Park in the hardcourt major, which has been pushed back three weeks and will start on February 8 due to strict pandemic health measures in Australia.
Five-time AO finalist Andy Murray tested positive for COVID-19 48 hours before his scheduled flight to Melbourne.
Upon arrival Down Under, the players and coaches will undergo immediate testing before embarking on a 14-day quarantine period before the Grand Slam begins.
Murray had been given a wildcard entry into this year's Open, the first major Grand Slam tournament of 2021.
Lisa Neville, Australia's Minister for Police and Emergency Services, confirmed on Twitter that Sandgren's positive result had been reviewed by health experts and "determined to be viral shedding from a previous infection, so was given the all clear to fly".
Responding to the absolute chaos Sandgren's tweets caused, the Australian Open explained that some people can still test positive to the virus months after first contracting it without being infectious.
Tennis Australia was forced to clarify the baffling circumstances, given rules stated that players, support staff and officials must test negative before boarding any of the 15 charter flights.
The flight from Los Angeles to Melbourne arrived yesterday morning, according to a screenshot of an email posted on Instagram by Mexican player Santiago Gonzalez. "I was sick in November, totally healthy now", Sandgren tweeted.
"For him to arrive late and to only get a couple of days of full court practice before the Australian Open, I don't think he'd take the risk on his body after going through what he has gone through to get to this point in his recovery".
Djokovic, Rafael Nadal and Serena Williams will be among a group of players involved in an exhibition event in Adelaide, South Australia state, on January 29.
Other players will be allowed to train under strict conditions and with supervision for up to five hours a day.
However, the ITF on Friday said Yastremska still has the right to have her provisional suspension lifted, and that if it was, she would be able to compete at Melbourne Park.
