Having drained his body down to lightweight for so long, two-weight world champion Devin Haney believes he'll be at his very best when making his welterweight debut against WBO beltholder Brian Norman Jr later this month.

Haney feels fresher than ever while winding down training camp for his first fight at the welterweight limit of 147 pounds.

The former undisputed lightweight champ can’t wait to demonstrate how this move up in weight will impact his ability to maximize his potential. If he can beat Brian Norman Jr. in their 12-round fight for Norman’s WBO belt, Haney will become champion in a third division.

“I think my power and punch resistance will be better, my mind will be more clear," Haney told The Ring. "I think I'll just be better overall."

Power and punch resistance are important components to Haney's plan for dethroning Norman in the co-feature of “The Ring IV: Night of the Champions” card November 22 at ANB Arena in Riyadh, Saudi Arabia.

Norman (28-0, 22 KOs, 1 NC) has won each of his three welterweight title bouts inside the distance, yet Haney is the most skillful, proven opponent of the emerging champ’s career. Haney (32-0, 15 KOs, 1 NC) hasn’t recorded a knockout since his fourth-round TKO victory over Zaur Abdullaev in September 2019.

The Henderson, Nevada resident’s unanimous points win against Jose Ramirez in his last fight marked the ninth consecutive time that Haney went 12 rounds. That bout was contested at a contracted catchweight of 144 pounds May 2 at Times Square in New York.

“I feel a lot better,” Haney said. “I had a great camp last fight. My weight cut went good, but I think that I’ll be even stronger, 147 is just the division for me now.”

Haney has accomplished plenty already in nearly 10 years as a pro. He believes, however, that fans and pundits haven’t seen the best of him yet because he suffered from draining his body down to 135 pounds or thereabouts for much of his career.

“I knew that I would be at 147 one day,” Haney said. “I didn’t know how long it would be or when it would, but I knew. My dad [and trainer, Bill Haney] has been telling me for a while that I was gonna be at my best at 147, I think he’s right.”

Knowing how much he sacrificed to drop down to the lightweight limit, Haney is nevertheless very proud of a 135-pound run including impressive victories over Vasiliy Lomachenko, George Kambosos Jr., Joseph Diaz Jr., Jorge Linares and Yuriorkis Gamboa.

Haney moved up to junior welterweight after he beat Lomachenko by unanimous decision in a highly competitive contest in May 2023.

“I’m definitely surprised with how long I was there,” Haney said. “I know how I did it. I was doing some crazy things to make the weight. Looking back at it now, I wonder how I was so successful doing it for so long.”

Norman’s sustained success at Haney’s new weight is among the reasons the Conyers, Georgia native is a slim favorite to win (-135/+110). Haney, 26, and Norman, 24, will meet in the third of four fights DAZN will offer on pay-per-view in the United States ($59.99) and the UK (£24.99).
