Harry Maguire, Donny van de Beek and Aaron Wan-Bissaka all trained with the Manchester United first-team squad ahead of their Europa League group game against FC Sheriff on Thursday night.
Erik ten Hag's side enter the penultimate match of Group E knowing that a win is likely to be required if they are to finish above Real Sociedad and avoid a play-off round next year.
United are expected to name another strong squad when they host the Moldovan side at Old Trafford and are set to be boosted by the possible return of a number of key players for the match.
