Manchester United will be without Edinson Cavani and Donny van de Beek for Thursday's crunch meeting with Real Sociedad.
The Red Devils will face Sociedad in Turin for the first leg of their Europa League last-32 tie due to coronavirus travel restrictions.
But two players who haven't travelled to Italy are Cavani and van de Beek, who are suffering slight injuries.
"Apart from that a couple of doubts," Solskjaer. "Anthony (Martial) and Scott (McTominay), so we will have to check them tomorrow. Donny and Edinson definitely not travelling.
"Donny and Edinson are injured - muscle injuries."
Star midfielder Paul Pogba was already ruled out of the game with a thigh injury, sustained in the draw with Everton last week.
