Kell Brook showed he’s big enough to fight at middleweight. Well, he actually showed he’s big enough to fight at light heavyweight when he tipped the scales at a whopping 176 pounds for his middleweight fight with Gennady Golovkin during the WBC’s mandatory 30-day weigh-in exercise.

A lot has been made of Brook, a welterweight titleholder, rising two weight classes to challenge Golovkin, a natural middleweight. But Brook showed his body is more than capable of packing on the pounds for the Sept. 10 showdown for Golovkin’s WBA, IBF and WBC middleweights titles at London’s 02 Arena on HBO.

Golovkin weighed a trim and ready 165 pounds on Wednesday. In his defense, Brook did seem to carry the weight well in a photo posted to social media, flexing his muscles after he apparently weighed in. Both men were required not to exceed 10 percent of 160 pounds (Brook was exactly 10 percent over) during Wednesday’s weigh in and 5 percent (168 pounds) seven days out from the fight.

Promoter Eddie Hearn, who handles Brook, had a little fun at the fans surprised reaction to his weight, tweeting that Brook had “seven pizzas before weigh in.” When the two posed off for a press conference last month in New York, Golovkin did appear taller, longer and broader than his opponent. But a month from the fight, he’s certainly not heavier.

“I’m very healthy at 160,” Brook told the Daily Mail. “I’m hydrated and eating well, nice sized meals that are giving me so much energy and I’m giving more of myself in the gym. I’m getting pushed in the gym and I’m delivering.”
