Last Saturday night, Kell Brook (36-2, 25 KOs) suffered his second consecutive defeat - and both losses saw the boxer deal with a fractured orbital bone.

Last September, Brook moved up by two weight divisions to challenge IBF, IBO, WBA, WBC middleweight champion Gennady Golovkin. After a competitive start, Brook suffered a fractured right orbital bone. Brook's corner stopped the fight in the fifth round. The boxer had to undergo surgery afterwards.

A week ago in Sheffield, Brook returned to the welterweight division to make a mandatory defense of his IBF title against Errol Spence. In the eleventh round, Brook took a voluntary knee, for the full count, after experiencing issues with his left eye. It was later revealed that he suffered another fractured orbital bone, this time to the opposite eye, and once again Brook is facing surgery and a lengthy time off.

According to Brook's head trainer Dominic Ingle, his boxer was not overly concerned about Spence's power during the fight.

According to Ingle, Brook stated that Golovkin was by far a bigger puncher than Spence - who has knocked out 19 of his 22 opponents. Golovkin has stopped 33 of his 37.

Against Spence, Brook's left eye was starting to swell badly in the second half of the fight.

Ingle explained that he allowed the fight with Spence to go on a lot longer than he did with Golovkin, because of the power difference - based on Brook's statements between rounds.

"We're talking about Spence Jr, not Golovkin. Kell did say that Golovkin's power was much more devastating. From what I could see, Spence Jr wasn't landing too many clean, full shots to the face," Ingle told Sky Sports.

"Don't forget Kell was two weight classes above against Golovkin. In my opinion that was more dangerous. As the rounds went on, eventually something hard and heavy would have hit Kell on the eye and I wasn't going to wait for that situation [with GGG]. Although Spence Jr was good, he wasn't as heavy a hitter as Golovkin."

Once the latest injury is healed up, Ingle fully expects Brook to return to the ring.

"I spoke to Kell afterwards and he said: 'I've got a few fights left in me'. I've got no concerns that he won't box again. He'll have the belief that his eye will become as strong as the other one. They've got to wait until the swelling goes down but he's got his operation planned. It's a slightly larger fracture [than the previous injury], but the surgeon says that will make it easier to operate on," Ingle said.
