Manchester United's Premier League clash with Brighton & Hove Albion, which is scheduled for Saturday afternoon, could reportedly also be called off.
The Red Devils were due to face Brentford in the league on Tuesday night, but the match was postponed due to a coronavirus outbreak in the camp, which came to light on Sunday morning.
Cristiano Ronaldo was allegedly among 17 first-team players present at the Carrington Training Complex on Wednesday for training under interim head coach Ralf Rangnick.
However, according to the Manchester Evening News, Saturday's game against Brighton could also be called off.
The report claims that the Red Devils are 'keeping the Premier League informed' of the situation in their squad, but it is 'too early for a decision to be made'.
Brighton have also had coronavirus issues in their camp, but the Seagulls are set to be in Premier League action against Wolverhampton Wanderers on Wednesday night.
