Manchester United's trip to Brentford on Tuesday is reportedly at risk of being postponed due to COVID-19.
The Red Devils are reported to have recorded a 'small number' of positive coronavirus tests before Sunday morning's training session, as the UK struggles to contain the Omicron variant.
The positive contingent are believed to have been sent home before training, but The Athletic claims that Ralf Rangnick could not lead a full session due to the situation.
The report claims that United only took part in individual, non-contact training, and Tuesday's Premier League clash with Brentford is now in danger of being called off.
United are not the only side to have been hit with a COVID-19 outbreak, with Tottenham Hotspur, Aston Villa and Leicester City all dealing with similar situations in recent days.
