Henrikh Mkhitaryan and Phil Jones did not take part in training today ahead of Manchester United's Europa League game against Feyenoord.
Jose Mourinho's side were put through their paces in front of the media before travelling to Holland for Thursday's group match.
According to BBC Sport, both Mkhitaryan and Jones were nowhere to be seen, but there has been no official word as to why the pair missed training.
It is believed that Mkhitaryan's thigh injury, which he suffered on international duty, flared up during last weekend's 2-1 defeat to Manchester City.
As for Jones, the defender has not yet made an appearance under Mourinho this season.
