Fletcher made his first appearance for Manchester United since being sidelined by ulcerative colitis last November in a friendly testimonial match against Aberdeen for Neil Simpson.
Despite the mix-and-match United XI losing 2-1 to Aberdeen, Fletcher's appearance in the second half gave Ferguson something a huge boost.
"We hope it's a start for him," He told the club's official website. "We don't know [when he will be fully fit] because we're all aware he has an issue which he has to deal with.
"But he's dealing with it very well at the moment and what we've seen tonight is encouraging for us."
He continued: "I'm delighted and you saw the response he got, which was fantastic.
"Well done to the Aberdeen supporters who gave him a rousing reception and he deserves that for his contribution to Scotland's national team as he's been terrific for them.
"For Darren, it's great to be back and I hope it's the start for him. We don't know as we're all aware he's got this issue he needs to deal with and he's dealing with it very well at the moment. What we've seen tonight is encouraging for us.
"It's been a quiet progress for the boy. He joined in training a couple of weeks ago and it's one of these situations where you say, 'Let's see how he does', because he has had a really difficult time in the last year.
"Therefore, I wasn't really placing too much hope in it but let's see how he does. He's got to the stage now where he feels he needs a game. He's been training really well.
"I let him join Scotland this week for their game but he wanted a game so I said: 'Come to Aberdeen and join up afterwards'."
Manchester United will start their season on Monday evening against Everton.
