Former world title challenger Harris, 33, scalped former British flyweight ruler Tommy Frank in May last year, stopping the Sheffield man in 10 exciting rounds to set up this brilliant fight against his 26-year-old Scouse opponent.
Unbeaten Butler, 11-0-1 (1), turned pro in 2018 and has hardly lost a round in the paid game before having a standout 2023 that saw him beat two very tough men in Craig Derbyshire and Matt Windle to claim European and Commonwealth honours.
Ahead of the much-anticipated show, which will see the winner in pole position for a shot at a world title, Harris says he expects Connor to try to outbox him for a points victory but is confident his bigger frame will be the deciding issue.
“From a young age, I’ve always sparred bigger boys. In Wales there aren’t many flyweights, so you have to take what sparring you can get and that’s exactly what I’ve been doing. I’ve always been strong and big at the weight.
“I’m a big flyweight and for this camp I’ve been sparring feathers with a similar style to Connor, box and movers. I’m sparring bigger people than Connor and I think I’m a bigger flyweight than him.
“He’s going to try and beat me over the distance. He won’t have a tear up with me, I’d be shocked if he does – but I can fight both ways anyway, everyone knows I can fight and box. I’ll be there all day long; he knows that and I’m pretty sure I’ll come out with the win on the 24th.”
