Manchester United are keeping the Premier League informed over the status of their squad after they returned to training at Carrington on Wednesday.
United remain in regular dialogue with the league after Tuesday's game with Brentford was postponed and Saturday's Old Trafford fixture with Brighton could also be called off.
While United are stressing it's too early for a decision to be made over the Saturday lunchtime kick-off, sources don't expect the situation within Ralf Rangnick's squad to have improved by then.
Indeed, it's now unclear whether United might have suffered more positive test results since the initial outbreak within the squad at the weekend.
