Former super middleweight champion Callum Smith is hoping to secure a path to a second world title when he faces Mathieu Bauderlique in their upcoming showdown.
Their fight, sanctioned as a WBC world title eliminator, takes place on Saturday night in Saudi Arabia.
The fight is featured as part of the undercard to the heavyweight rematch between Anthony Joshua and Oleksandr Usyk.
In his last fight, back in September, Smith made his in-ring debut at 175-pounds.
It was Smith's first bout since losing a twelve round decision to Saul 'Canelo' Alvarez.
After that fight, Smith admitted that he seriously struggled to make the limit of 168.
Smith made a big impact in his light heavyweight debut, with a brutal knockout of Lenin Castillo.
He views the fight with Bauderlique, who holds the EBU title, as a must-win situation.
"It's must-win. I think every fight is must-win at this stage in your career. I'm in a busy division, a packed division where there's a lot of fighters waiting for a shot at the world title. A loss here puts me at the back of the queue - and it's a very big queue to go to the back of. A win here puts me at the front of the queue, it puts me next in line to fight for the world title. That's the goal. I've been there before down at 168 and I believe I'm good enough to do it at 175," Smith said.
"It's a must-win and I'm excited, it's a big show and a big platform to perform on. Hopefully I can get the business done and move onto a world title. It's been good to be here and good to get back here. Obviously I've got the best memories from being here, becoming a world champion.
"There's a good buzz around the place this time round. Obviously it's a great main event but I'm here to do a job and that's win. I left here last time as a world champion. I believe I'll leave here this time ready to fight for a new one."
