The Champions League last-16, second-leg matches between Manchester City and Real Madrid and Juventus against Lyon next week have been postponed due to the coronavirus outbreak, European football's governing body Uefa has confirmed.
Real said earlier on Thursday that it had sent all of the members of its football and basketball teams home into quarantine after one of the sports club's basketball players tested positive for the coronavirus.
Juventus defender Daniele Rugani tested positive for coronavirus on Wednesday, leading the Italian club to quarantine their entire squad.
"Following the quarantine imposed on players of Juventus and Real Madrid, the ... matches will not take place as scheduled," Uefa said.
"The decision to postpone Tuesday's game was made in conjunction with Uefa and follows confirmation that players from Real Madrid will self-isolate for fifteen days," City said in a statement.
"The club sends its best wishes to the players and staff at Real Madrid's football and basketball teams."
Both matches were due to take place on Tuesday, March 17.
City have a 2-1 lead from the first leg in Madrid on February 26 while Juventus trail Lyon 1-0.
As it stands, Wednesday's two last-16, second legs between Bayern Munich and Chelsea and Barcelona and Napoli are still set to go ahead behind closed doors.
The news follows a decision taken earlier in the day by La Liga to cancel all matches in Spain's top two divisions for at least two weeks due to the coronavirus pandemic.
Thursday's Europa League matches between Inter Milan and Getafe and Sevilla and Roma had already been postponed due to fears over the spread of the Covid-19 virus.
City's Premier League match with Arsenal that was due to take place on Wednesday is the only Premier League game to be abandoned so far after Arsenal players came into contact with Olympiakos owner Vangelis Marinakis, who tested positive for the virus, after a Europa League match two weeks ago.
Uefa is to have a crisis meeting on Tuesday with representatives from all 55 national associations and club and player bodies to decide how national leagues, European competitions and Euro 2020 should proceed.
