Anthony Martial and Aaron Wan-Bissaka were not photographed with the rest of the team, as Manchester United players flew on Wednesday afternoon, before the last 16 Europa League clash with LASK.
Martial did not train at Carrington during the open session and is a doubt for the game in Austria.
However, Odion Ighalo made the journey and it is very likely that it will start with Ole Gunnar Solskjaer's men.
Jesse Lingard and Diogo Dalot were also not seen as part of the traveling squad.
Tahith Chong has traveled to Austria along with her companions Mason Greenwood, Brandon Williams and Angel Gomes.
United enters the game undefeated in its last 10 matches in all competitions.
Confirmed members of the United team to face LASK:
De Gea, Romero, Obispo, Williams, Lindelof, Maguire, Shaw, Tuanzebe, Bailly, Gomes, Pereira, Matic, McTominay, Fernandes, Fred, Mata, Greenwood, James, Chong, Ighalo
