LAS VEGAS – Kell Brook can’t comprehend why his age has been mentioned among his supposed disadvantages against Terence Crawford.

Brook turned 34 six months ago. Crawford, who’ll box Brook on Saturday night, turned 33 on September 28.

“He’s only a year younger than me,” Brook told BoxingScene.com after a press conference Wednesday at MGM Grand. “Everyone’s going on about age. He’s not a spring chicken himself.”

The undefeated Crawford is widely viewed, however, as a more physically preserved fighter than Brook. The three-division champion hasn’t endured the types of physically grueling battles Brook experienced against Gennadiy Golovkin and Errol Spence Jr.

Golovkin stopped Brook in the fifth round of their middleweight title fight in September 2016 at O2 Arena in London. Brook suffered a fractured orbital bone around his right eye against Golovkin, which caused his trainer, Dominic Ingle, to throw in the towel during the fifth round.

Brook then suffered a broken left eye socket in his following fight, an 11th-round knockout defeat to Spence in May 2017 at Bramall Lane, an outdoor soccer stadium in Brook’s hometown of Sheffield, England.

The former IBF welterweight champion hasn’t had any issues with his surgically repaired orbital bones in any of his three fights since Spence stopped him. He joked that his face is “made of steel” and said he doesn’t even think about those serious injuries anymore.

Brook (39-2, 27 KOs) is a huge underdog against Crawford (36-0, 27 KOs), but he definitely doesn’t think age should be considered a factor in assessing their 12-round, 147-pound championship match.

“I don’t know why people are talking about age,” Brook said. “There’s 18 months between us. Listen, people just come out with this just to keep their job. They just think that because I’m a bit older [than Crawford], just mention it, you know? He’s a bit younger, mention it. He’s a bit taller, mention it. He’s a bit lighter, mention it. It’s just an age. There’s a year-and-a-half between us. What’s that? We’re all adults.”

ESPN will televise Crawford-Brook in the United States as the main event of a three-bout telecast Saturday night (10 p.m. EST; 7 p.m. PST). Premier Sports 1’s coverage of the Crawford-Brook card is set to begin at 12:30 a.m. GMT Sunday in the United Kingdom.
