After a pretty much flawless performance from the Republic of Ireland international, his attempted hook clear with 11 minutes of normal time remaining spun high in the air and a big leap from Robbie Fowler was enough to disrupt Kasey Keller from gathering the ball. The former England international striker then had the relatively simple task of knocking the ball into an empty net.
"Obviously, my clearance wasn't too good but we came through," reflected Gary, before giving a typically honest assessment of the mishap. "I thought I'd deal with it like a defender should, hook it clear and defend from wherever the ball goes. It came off the outside of my left foot, spewed up in the air and Kasey and Robbie Fowler went up for it. Fowler did a terrific leap and was able to tap into the net."
City were buoyant after the goal and the team, and Gary himself, showed great character to withstand the late onslaught - Gary launching himself into at least two crucial blocks.
"You just want the ground to swallow you really, but you've got to buckle down, defend and make sure you get the victory - which we did.
"I thought the game was going really well for me until the incident. I felt that I defended alright and thought I blocked well - all the lads threw themselves between the ball and the goal and it worked out for us.
"It is the best I've felt in a long time and the fact that I'll come straight in if Deano or Anthony are struggling has given me great confidence.
"I think in the first half an hour we were brilliant, they got back into it because they've got so many quality players and thankfully we got the win in the end.
"We played some lovely stuff and the midfield was working hard - Ledley and Gus in the middle really worked their socks off. It was great for us and a two-goal lead gave us something to protect."
Gary agrees that the team now need a repeat performance against Wolves in the Premiership on Saturday in order to get a result that will hopefully spark a push up the table in the forthcoming weeks.
"I think we will," he insisted. "Wolves will be looking to bounce back from their result on Tuesday and it is big game for us now.
"We've got a few big games coming up and hopefully we will get a victory that will lead us on to having a good season."
Gary Doherty admitted that he wanted the 'ground to swallow him up' after his miscued clearance gave Manchester City a Carling Cup lifeline on Wednesday evening.
