Former welterweight champion Kell Brook (36-2, 25 KOs) has been taking a lot of heat from the critics, and some fighters, for the outcome of last Saturday's fight with Errol Spence.

Brook was making a mandatory defense of his IBF welterweight title against Spence before a crowd of 27,000 at Bramall Lane in Sheffield.

The fight was competitive for seven rounds, before Spence started taking over around the eight. Brook went down in the tenth, and then took a voluntary knee for the full count in the eleventh round.

It was revealed after the fight that Brook had suffered a fractured left orbital bone.

The boxer started experiencing double vision in the ring and felt it was necessary, for his health, to pull himself out of the fight.

In a weird circumstance, Brook was coming off a five round stoppage loss at the hands of middleweight king Gennady Golovkin from last September - and in that fight Brook had fractured his right orbital bone. Brook had to undergo surgery and needed several months to fully recover.

Brook admitted that during the fight with Spence, he started having flashbacks of a conversation that he had last year with his doctor - who warned Brook that he could have gone blind in the fight with Golovkin.  

He became concerned that he might jeopardize the vision in his left eye if the fight continued any further.

John Murray, known for his all-action fighting style, retired from the sport in 2014 due to a detached retina. The injury left his blind in his right eye.

Murray absolutely backs Brook in his decision to find an early exit when his vision became impaired.

“No one knows what pain he felt in there, you can’t sit on the couch and say he should slug it out for a couple more rounds when you don’t know what that pain’s like. If he’s got a fractured socket obviously in the back of his mind he’s thinking ‘I might go blind.’ He’s got to take into consideration his own health,” Murray told Boxing News.

“With my injury, I didn’t know I was going to be blind, it was the last thing on my mind, I just thought it was swollen and shut tight. If I knew I was going to go blind I’d have never taken another fight. If he’s worried about going blind he’s right to stop the fight. It’s only a sport at the end of the day and you only get one pair of eyes. It’s not as if you go blind, you get more money. Nothing like that. You just lose your eye. In boxing, once you go blind, you go blind and that’s it. There’s no need to be a hero, you’re not going to get anything for it.”
