JACK Catterall is on a Las Vegas spying mission as he plots to become world champion.

Edinburgh’s IBF and WBA World super-lightweight champion Josh Taylor meets WBC and WBO title holder Jose Ramirez tonight and Catterall will be front row making sure the winner doesn’t duck out.

The winner has vowed to face WBO mandatory contender Catterall next after the Chorley man agreed to step aside.

“It is a massive fight, hopefully it is a good fight and I can let everyone know I’m serious about fighting the winner," said Catterall, who has won all 26 of his fights.

“I will do some training, sparring and ultimately watch the fight. After the weekend we will have a clear direction of where we’re going.

“I stepped aside on the promise that I will get the winner and I am under no illusion because anything can happen, but ultimately I have allowed them to create this big undisputed title fight.

“I have beaten everyone in front of me, done everything asked of me on my side.”

The 27-year-old believes a Taylor win would set-up a huge England v Scotland battle, but has doubts about Ramirez keeping his word.

“I hope Josh wins and hope he is a man of his word,” said Catterall, who will spend two weeks in Las Vegas training.

“It’s been talked about Taylor having a homecoming fight at Edinburgh Castle and I am bang up for the challenge.

“I could be wrong and I hope I am wrong, but I don’t think Ramirez will give me an opportunity. I think he probably has other plans.

“Taylor has publicly thanked me for stepping aside and allowing this big fight to happen. Hopefully he can get the job done and we can get it on.

“I don’t mind travelling and Edinburgh for a scrap would be brilliant. I have already planned English drummers to walk me out.”
