Dillian Whyte never let his violent knockout loss to Alexander Povetkin demoralize him.

Whyte wanted their rematch to take place as soon as possible. It’ll finally happen Saturday night after multiple postponements, but Whyte didn’t spend the past seven months dwelling on the stunning defeat that cost him his spot as the WBC’s mandatory challenger and that sanctioning organization’s interim title.

London’s Whyte instead focused on correcting the tactical mistake he believes enabled Povetkin to unload the picture-perfect left uppercut that suddenly ended their August 22 bout in Brentwood, England. Oddsmakers seemingly agree with Whyte (27-2, 18 KOs), who has been installed as a 3-1 favorite to beat Povetkin (36-2-1, 25 KOs) in their second fight.

“It’s the most important fight of my career,” Whyte said during a press conference Thursday in Gibraltar, where they’ll fight at Europa Point Sports Complex. “You know what I mean? But like I said, this is boxing. You understand? I’ve been through ups and downs my whole life, so I’m used to bouncing back. I’m used to coming back and proving people wrong. I’m used to showing people what I can do if they’re writing me off. So, I’m good. I’m easy. You know what I mean?”

The rematch between Povetkin, 41, and Whyte, 32, is the main event of a Sky Sports Box Office show in the United Kingdom (£19.95; 6 p.m. GMT). DAZN will stream it in the United States (2 p.m. ET; 11 a.m. PT) and approximately 200 additional countries.

Russia’s Povetkin overcame two fourth-round knockdowns to upset Whyte in their first fight. Whyte was well on his way to a knockout victory of his own, but a seemingly depleted Povetkin knocked him unconscious with a lethal left uppercut early in the fifth round.

Povetkin’s punishing punch dumped Whyte flat on his back, beneath a bottom rope, and abruptly ended a fight that took place on the grounds of Matchroom Boxing’s headquarters.

Whyte suffered the second knockout defeat of his nine-year pro career versus Povetkin. Anthony Joshua’s right uppercut viciously knocked out Whyte in the seventh round of their December 2015 bout at O2 Arena in London.

“People say, ‘Oh, the defeat, this, that and the other,’ ” Whyte said. “I’m like, ‘Yo, like it’s nothing. I’m doing something. I’m changing my life. And I’m still improving. I’m constantly improving, always improving. And obviously, the guy’s a good fighter. You know what I mean? Top amateur, gold medalist, world champion and all that stuff. But I’m still learning. I’m still improving. I’m still getting better every day. And Saturday, I’m coming to leave it all on the line once again.”
