The Scotland international midfielder has missed nine matches
after being floored by a virus in early March.
But he has been training for more than a week now - and United
boss Fergie hopes to have him back by the end of the month.
The Champions League semi-final at Schalke next Tuesday may come
too soon.
But United then face title rivals Arsenal and Chelsea in the
space of a week - with the second leg against the Germans
sandwiched in between.
Fergie said: "Fletcher is back in training, he's not doing a lot
but has put the weight back.
"He's had a terrible virus. It's one of those energy-sapping
viruses that you can get and he lost a bit of weight.
"But that weight is back on again now and we'll look forward to
getting him back."
The United boss said last week that Fletcher was 'a couple of
weeks away' - putting the trip to Germany or the Emirates on
Fletcher's horizon.
