uventus forward Cristiano Ronaldo has tested positive for coronavirus, the Portuguese Football Federation (FPF) has announced.
The 35-year-old Portugal forward is “doing well, without symptoms, and in isolation”, the FPF said in a statement.
Portugal face Sweden in a Nations League group game on Wednesday.
The remainder of Fernando Santos’ Portugal squad have tested negative for Covid-19 and are available for selection.
Portugal played out a 0-0 draw with France in Paris on Sunday and are top of the group, level on points with the world champions.
The Portugal captain became the first European to score 100 international goals in men’s football when his side beat Sweden in the reverse Nations League fixture in September.
As a result of his period of quarantine, Ronaldo is also set to miss Juventus’ Serie A fixture at Crotone on 17 October and his side’s opening Champions League group game against Dynamo Kiev on 20 October.
The Italian champions then face Verona on 25 October.
On Monday, Ronaldo posted a selfie with the Portugal squad on social media on Monday night with the caption “United on and off the field!”
Cristiano Ronaldo is the latest high-profile footballer to test positive for coronavirus.
Despite surging cases of Covid-19 across the globe, many footballers have left their clubs to play international games.
However, some clubs have not released players to play for their countries, including the Austrian side RB Salzburg whose players were called up for Mali, Cameroon, Zambia, Austria and Hungary.
On Monday, Ronaldo posted a photo to social media of him sharing a meal with his Portugal teammates.
The forward has scored three league goals in two games for Juventus so far this season — one against Sampdoria and a brace against AS Roma.
He also scored twice as Portugal defeated Sweden 2-0 in the Nations League last month.
With his first goal against Sweden, Ronaldo became the second player ever to reach the milestone of 100 international goals. He is now eight goals behind the all-time international record of 109 set by Iranian Ali Daei.
Earlier this year Ronaldo flew back to his native Madeira when coronavirus cases started to rise across Europe and football was suspended, according to Reuters.
He then helped Juventus lift the Serie A title following the league’s resumption.
