Carslaw, 30, has finally earned another crack at the British Super-Welterweight title after an agonising three-year wait.

The Paisley puncher last fought for the title in June 2012 but lost out to Brian Rose.

Now he will take on Welshman Williams, not only for his Commonwealth belt, but for the vacant British Super-Welterweight title too.

The fight is to be staged at the MEN Arena, Manchester, on December 19 and Carslaw cannot wait.

He said: “I can’t wait to get to Williams and was over the moon when I heard the news I’d be fighting him for his Commonwealth belt and with the Vacant British title also on the line.

“There’s no way I’m letting that British belt slip past me a second time after waiting over three years since the Rose fight, this time I’ll make sure the Lonsdale belt comes back home to Scotland with me.” The fiery Wales-Scotland showdown features on the double world title show on the undercard of the potential thriller between WBO World Middleweight champion Andy Lee and Billy Joe Saunders and Liam Smith’s WBO World Super-Welterweight title defence.

Opponent Williams, 23, has his first fight in over year following surgery on his right hand after his first round stoppage of Michael Lomax in November last year to win the Commonwealth title.

During 2014 he was, however, in devastating form with stoppage wins over Yuri Pompilio, Ronnie Heffron, Stepan Horvath and Lomax, and is now raring to get back his world title trail.

He said: “I’ve been out of the ring for a while, so I’m looking forward to making my return and getting my name back up there again.

“I was on a good run of KO’s against Pompilio, Heffron, Horvath and Lomax so Carslaw will be a good fight back for me and bring the best out.

“My right hand feels brand new now and I’m punching harder than before with equal confidence in sparring and hitting the bags, so I’m not afraid to let it go on the night against Carslaw.

“He’s a good all-rounder and decent at what he does, but to me he’s not spectacular in anything particular and I believe that my strength and punching power will be too much for him on the night.” He added: “Just like the rugby, a Wales v Scotland showdown in the boxing ring is bound to be an explosive clash and one that will bring out the best in us.

“I’m confident that I’ll be coming away the winner and continue on my road to the world title.” Carslaw, though, is convinced he’s got the correct tools to bring Williams to his knees.

He said: “Williams is a good, strong, fighter, he hits hard, but he’s one dimensional. I’ll come up with the game plan to beat him.” He added: “It’s going to be a massive fight between me and Williams with plenty of national pride on the line, the best man is going to win on the night and that is me.”
