Cristiano Ronaldo went into self-quarantine in Portugal after his Juventus teammate Daniele Rugani was tested positive for the coronavirus, reports Business Insider.
According to AS, Ronaldo travelled to Madeira on March 9 to visit his mother who recently suffered a stroke just one day after Juventus had beaten Inter Milan in a match behind-closed-doors at the Allianz Stadium in Turin.
Juventus earlier said in a statement that Rugani, the 26-year-old Italy international, who played in matches against Brescia and SPAL in February and was on the bench for Sunday's home game against Inter Milan, had not shown any symptoms of the virus.
Ronaldo was expected to fly back to Italy on Thursday. But he will now remain in Portugal to self-isolate himself following the news of Rugani's illness.
A source close to Juventus told Reuters that the players would now have to be isolated and put into quarantine for two weeks.
That would mean the Champions League quarter-final second leg at home to Olympique Lyonnais next week but that match is now in doubt.
The Italian government has banned all sporting events, including Serie A, until at least April 3, in a bid to contain Europe's worst outbreak. The most recent games were played on Sunday.
