This fight will mark the first appearance in a boxing ring for Brook since he lost his IBF title previous year to American Errol Spence Jr at Bramall Lane.
Brook marked the face of Rabchenko at the end of the first round with a painful jab after easily side-stepping a wild opening from his opponent. He's one of those kids you won't get a lot of credit for beating him but it will take a hell of a lot to beat him.
After bad back-to-back losses, and his trainer Dominic Ingle stating he wouldn't fight more than three more times, Brook needs a victory if he is to get one final tilt at another championship.
"Everyone wants to see that fight". I was in Sheffield, we'd sold a load of tickets and we were in a football stadium - but going from Middleweight down to Welterweight was too much and it just drained me.
'I was a proud champion and I never duck anyone, Errol is a class act and will dominate at 147lbs - hopefully I can get the rematch at super-welterweight though.
"I'm built to box".
And Brook admits he wants the fight to happen regardless of the weight. Rabchenko is a risky guy, he's no mug and he can really bang. "The feeling I get from going out there, hearing "All of the Lights" and doing my thing in front of all of the fans, it's wonderful for me, that's my drug and I can't wait to get back in there".
"I was going to ask him to have a snowball fight, but then I thought twice".
But there was no such injury drama on Saturday night, as "The Special One" returned to the win column in his native Steel City and claimed the 26th knockout of his career without breaking a sweat.
"The eye has healed very well. It's held up in sparring and I don't think about the eye injuries at all", added he Sheffield fighter. "I wouldn't be boxing if I wasn't given the all clear by the doctors, I wouldn't put my family or myself through that".
