Marc McCullough knows that defeat on Saturday night in Belfast would be the end of the road - but the Belfast featherweight believes this is only the start of the journey.
McCullough - after his defeat to Issac Lowe in Manchester in February - has changed camps and trainer in a bid to get his career back on track as he faces Luis Lugo for the vacant WBO Inter-Continental title at the Belfast venue.
And McCullough believes this is the start of something special.
“I want to show how much I’ve changed. I’ve been working on lots of things in the gym, rekindling good habits.
“I’ll be back to my boxing. Nice and sharp, good defence.
“Before I felt tired and drained going into fights, burnt out. This time, I’m entering with so much confidence.
“Lugo’s lost just five of 25 in pretty decent class so, touch wood, it’ll be a great scalp that’ll push me right back up there.”
And McCullough admits that the change of opponent has meant he has had to rethink his plans for tonight.
“Initially, I was due to fight Michael Roberts from Scotland (unbeaten in 19) but he pulled out and stylewise it’s a complete change. I trained for a boxer but I’ve landed with a brawler.
“My coach has studied the Mexican and warns that he’s a hard puncher who’s unbeaten in his last three.
“These Mexicans have to fight simply to survive so I doubt I’ll have to go looking for Lugo which was the case with many of the Eastern Europeans I faced earlier in my career.
“These Mexicans all come to get you and are notoriously hard and tough. This one apparently made his pro debut when he was just 13,” he added.
And the Belfast fighter says he would love to avenge his defeat to Lowe.
“I would take that fight tomorrow if it was offered to me. Things went wrong and I would do things a wee bit differently.
“Lowe did what he had to do that night but I would take the fight again straight away,” he added.
