After fresh testing revealed no positive instances within the first-team group, Manchester United players and staff will be released from isolation and returned to training immediately.
The pre-season friendly against Preston North End on Saturday was called off after a small number of players and staff were suspected of testing positive for Covid during a round of lateral flow testing on Thursday.
Following PCR tests, no positives were found in the group, and all individuals impacted will now return to training.
A club statement read:
"After further testing yesterday [Thursday] and today [Friday], we can confirm that there are no positive cases within the first-team group.
“Following consultation with the Premier League, they are satisfied that all COVID protocols have been followed correctly and the squad can return to training immediately."
