Fans and reporters are anxious to see how Kell Brook bounces back from his technical knockout loss to Gennady Golovkin.

Brook’s trainer is convinced that he’ll be better in his comeback bout than Golovkin looked against Daniel Jacobs on Saturday night at Madison Square Garden. Dominic Ingle and Brook claimed Wednesday during a press conference for his May 27 fight against mandatory challenger Errol Spence Jr. (21-0, 18 KOs) that the IBF welterweight champion “knocked the stuffing out of” Golovkin during their September 10 fight in London.

Brook (36-1, 25 KOs), who moved up two weight classes to challenge Golovkin for his middleweight titles, had some success against a slower, defensively deficient Golovkin early in their fight. Golovkin’s damaging punches fractured the orbital bone around Brook’s right eye, however, and Ingle threw in the towel during the fifth round to spare Brook irreparable damage.

That didn’t prevent Ingle from stating Wednesday that it was Golovkin, not Brook, who’s not the same man as he was before they fought six months ago at O2 Arena. That was obvious, according to Ingle, while watching Jacobs test Golovkin throughout their 12-round fight, which ended Golovkin’s 23-fight, eight-year knockout streak.

“We all watched the Triple-G fight last weekend,” Ingle said. “For me, you could see after being in the ring with Kell, there was something missing [in Golovkin] in that fight. You know, Kell had knocked the stuffing out of him and he wasn’t the same fighter. I don’t think anybody gave Daniel Jacobs a chance in that fight. And, you know, watching Daniel Jacobs you could see he picked a bit off Kell – switching, rolling, moving, grabbing, holding through that fight. A lot of people thought he won that fight. Yet apart from the injury, he didn’t really make a dent on Kell.”

Going the distance against Brooklyn’s Jacobs (32-2, 29 KOs) also made Brook believe their fight took something out of the 34-year-old Golovkin (37-0, 33 KOs), who won a unanimous decision (115-112, 115-112, 114-113).

“Nobody’s been going the distance with him, so I do believe I knocked the stuffing out of him in that fight,” Brook said. “I think I put the blueprint out there. And I remember watching bits of footage, and even Jacobs mentioned that his friends were on the phone to him, saying, ‘Kell Brook’s upsetting Golovkin,’ and everything else. So I believe they went in there knowing that he’s not invincible.”

If he hadn’t suffered such a severe injury, Brook thinks he would’ve upset Golovkin. Brook was ahead of Golovkin, 39-37, on one scorecard and the other two judges had their fight even when it was stopped.

“I was gutted because the fight got stopped basically,” Brook said. “I’m just gutted to [not] see how I would’ve done if I could see. I believe I gave it to Golovkin, and I could tell at the end of the rounds and during the fight that he was slowing down and I think I was gonna take over.”
