Manchester United duo Nemanja Vidic and Rio Ferdinand have missed training ahead of Wednesday's Champions League encounter at home to Real Sociedad.
Vidic is believed to be suffering from a calf injury, while Ferdinand is struggling with a groin problem.
Meanwhile, Tom Cleverley and Danny Welbeck also sat out the session at the club's Carrington training complex.
United currently sit at the top of Group A on goal difference after taking four points from their opening two matches.
