Trent Dumont has described the feeling of kicking his first goal in North Melbourne colours as “unreal”.

The midfielder came onto the ground in the last quarter of the Roos’ win against the Cats, and was immediately into the action.

Just minutes after setting up a goal for teammate Ben Brown, Dumont stood tall in the heat of battle.

"The ball kind of just landed in my lap. I was trying to handball it off again, but then a player peeled off and went to Browny (Ben Brown) so there was only one option after that - to have a crack at the goals,” he told NMFC.com.au after the match.

"It was unreal. It was unreal. I didn’t expect it to come off so well. It just kind of happened."

Dumont's goal put North eight points clear midway through the final term, and his teammates came from everywhere to celebrate.

Originally named as emergency, he only got his chance after Jamie Macmillan and Luke McDonald were withdrawn from the side due to injury.

"I came into the club (on Saturday) and thought I’d be playing VFL or the carry-over emergency for today’s game.

"I was just eating breaky and Codge (Neil Connell) our player welfare manager told me to go up to Brad’s (Scott) office and I kind of had an idea of what would happen from there.

"I was happy to hear the news from Brad that I’d be brought in to play."

Dumont revealed his nerves ‘weren’t too bad’ leading into the game, but intensified when he got his chance in the final term.

"I knew I was sub, so the likelihood of coming on early wasn’t high. I felt a little bit more nervous when I was actually out there.

"Considering they’d already played three quarters, it was a lot faster than I had anticipated.

"I just ran as hard as I could and managed to get on the end of a few, but they were still moving well both sides."

The midfielder finished with five disposals and a goal, but perhaps more importantly wasn’t overawed by the experience.

"Trent Dumont seized his opportunity today," North coach Brad Scott said after the match.

"It was only a small one, but he was clearly really important for us at the end of the game there.

"We’ve worked really hard with him and he’s worked really hard over the last couple of years to get an opportunity. We feel now that he’s ready to play AFL footy."
