Town require a win over the Bluebirds to know for sure they have a play-off place, and Bent, Town's top scorer for the season with 15 goals, knows just how important it is that Town get the right result.
Speaking to the Official Club Website Bent said: "It's a massive game, the biggest of my career. I've seen the pictures of the Play-Off Final when the Club won at Wembley four years ago and it would be great to be part of that again.
"But we have a big game against Cardiff first and we know it's going to be a tough one for us."
