Wayne Rooney, Anthony Martial and Marouane Fellaini have all resumed training as Manchester United prepare to host PSV in the Champions League on Wednesday.
Rooney was forced to sit out a 2-1 win away to Watford in the Premier League on Saturday due to illness, while Martial was unavailable after picking up a foot injury in France's international friendly loss to England last week. Fellaini missed the game at Vicarage Road due to a calf problem.
All three are now expected to be available for selection when the Eredivisie title-holders visit Old Trafford, having taken part in training on Tuesday without any problems.
However, Ander Herrera, Phil Jones and Michael Carrick - all of whom sustained injuries before or during the last-gasp win at Watford - had to miss the session.
United will be looking to secure their place in the knockout stages when they meet PSV.
Louis van Gaal's men sit top of Group B with seven points from four games played, one point clear of the second-placed Eredivisie champions. Wolfsburg are third, level on points with PSV, while CSKA Moscow are bottom of the group on four points.
