The Irish international was in fine form and looking set for a long spell in the first team when his short-term dreams were shattered against Torquay in the Worthington Cup.
Even though he returned towards the end of the last season and has remained injury-free so far in this campaign, Gary still feels he has a lot of work to do before his fitness and form levels really pick up.
Asked how close he feels towards optimum fitness, Gary definitely leans towards the conservative, which is difficult to believe for anyone that witnessed him galloping around and scoring for the reserves in attack against Chelsea on Monday.
"I wouldn't put it near the 90s, percentage-wise, probably about 75 per cent I think. I've got a long way to go to get back to what I was, but that only comes with games.
"I'm feeling good so with the more games I play the fitter I'll become.
"It's going alright. It's still all about getting my fitness up as, even though I've played up front a few times, it is still a fairly new position for me because I keep having to swap."
Gary is generally last off the training pitch at Spurs Lodge and the rewards were there for everyone to see at Stevenage. He hopes this will lead to a first team return, but he reveals he hasn't been happy with his senior contribution so far this season.
"I try and work hard and I'm always doing extra in training. Hopefully I'll get the benefits of that.
"I need to take my form onto the next game and the one after that. Then, hopefully, I can roll forward into the first team.
"When I've played I haven't really been happy with my performances so I can't really knock on the gaffer's door and say I need to play.
"Hopefully I can put in a few good reserve performances and remind him of what I can do in certain situations and see how it goes from there."
Gary Doherty feels that he has a 'long way' to go fitness-wise before he gets back to where he was before sustaining a broken leg early last season.
