Rio Ferdinand returned to light training at Manchester United on Tuesday but could still face up to two weeks out with a knee injury.
Goal understands that the defender took part in a light fitness session with club physios at Carrington after not travelling with the squad who lost 2-1 to Sunderland at the Stadium of Light.

The nature of Ferdinand's injury had caused fears that he had suffered ligament damage but United are confident that he has only suffered heavy bruising.
Club staff expect the veteran defender to be out for no longer than a fortnight and will gradually build on his training schedule as he returns to full fitness.
United next face Swansea on Saturday before travelling to Chelsea on January 19, though medical staff expect that he will be fit to face Sunderland in the return leg of the Capital One Cup semi-final following those matches.
Phil Jones is nearing a return to full fitness ahead of Saturday's rematch with the Swans, having been ruled out of the champions' festive fixtures, though Jonny Evans limped off the pitch in Tuesday's 2-1 loss to the Black Cats.
