The 26-year-old was injured in United's 2-1 defeat at Stoke City on February 1, but made his comeback on Monday as an over-aged player in an Under-21s match against Aston Villa.

"It's still a bit tender but nothing too serious," Evans told MUTV. "It was good to get 60-odd minutes [on Monday] and to get a bit of game time.
"It's been frustrating as it's been over two months now since I last played. I don't know if I'll be involved or not [against Bayern]. Maybe it's touch and go but I just hope the lads can do well and get a good result.
"In terms of my injury, it may have come too soon for me but, in terms of excitement-wise, the game cannot come quickly enough - especially for the fans and players. Everyone is looking forward to it."
United have struggled in the Premier League this term, but performed well when holding European champions Bayern to a 1-1 draw at Old Trafford last week and Evans is confident ahead of the second leg.
"We've had a great record in Europe but I think the mentality of the players has always been the case that we're not underdogs," he added.
"We're Manchester United and want to make sure we put on a good performance. Teams have to make sure they try to beat us and teams do fear us.
"We know it's a big task against Bayern but we've had that experience of nights like this before. I think the lads still fancy themselves to win."
