"I had eight weeks out injured but I was professional, I did everything right and I feel good," the 24-year-old said.
"There is nothing like match fitness and like I said, I was starting to feel it on 60 minutes but hopefully if I'm playing next week (against Leicester) I'll be able to complete the 90 minutes," he added.
Mason, who earned his one England cap in a friendly against Italy in March, picked up the injury after a clash with Jack Wilshere during a training session with the England team in June, forcing him to pull of international fixtures that month.
Mason said his fitness would improve after getting more than an hour against Stoke.
"Perhaps I blew up in the second half (against Stoke), my legs went a bit but I'll feel better for it next week and hopefully I'll chip in again," he added.
