Darren Fletcher played the first half of United's 0-0 draw with Arsenal in the reserves.
"It's great to be back and get minutes under my belt, back playing football again," he told MUTV.
"I think it's a good, positive thing for me as it's been a while and I just wanted to get back out there and play for the reserves.
"I got a good 45 minutes and can hopefully keep pushing forward to get back into the plans for the first team.
"I don't want to rush too quickly. I'll speak to the doctor and the manager tomorrow and see how I feel and take it from there."
