Hutchinson and Buatsi, 33, first met on the undercard of Daniel Dubois v Anthony Joshua at Wembley Stadium in September 2024.
Dubois’ stunning fifth-round knockout victory to retain the IBF heavyweight title rightly dominated the headlines.
But Hutchinson and Buatsi had earlier laid the table with a remarkable back-and-forth contest.
Hutchinson climbed up from the canvas twice to make the final bell – taking rounds in between each of those knockdowns – but ultimately came away on the wrong side of a split-decision.
Their rivalry has been bubbling away nicely over the past two years, with insults traded across social media, and Saturday’s rematch now offering up world honours.
“This time I’m going to put the performance on I should have done two years ago,” Hutchinson said.
“So he’s going to be meeting a different Willy Hutchinson this time. I’m going to be there and I’m going to be taking that world title back home with me, I can tell you that.
“It’ll be good to get my revenge back on him, but more important is to become a world champion. It’s kill two birds with one stone.”
Hutchinson has rebuilt since that loss, stopping Jeffers and earning a decision win over Ezra Taylor.
Olympic bronze medallist Buatsi, meanwhile, fell to his first professional defeat against Callum Smith, although he bounced back against Zach Parker.
“Joshua Buatsi is not a person I would be overthinking about. He’s never looked too good, has he? He took a very bad loss against Callum Smith and then that other lad he fought (Zach Parker) made him look terrible, didn’t he?” Hutchinson said.
“The best Joshua Buatsi that is to come will be on 7 November and the best Willy Hutchinson will be there on 7 November and the cream will always rise to the top.
“The hard work’s done. The hardest thing of fighting Joshua Buatsi was the camp I just did. I’ve just got to go and do my job, but I should make an easy night’s work of it.”
