Brook, 31, went down to one knee and was counted out after breaking his eye socket two fights running (the opposite one this time) and Witter has now raised questions regarding the ex-welterweight title holder’s future.
Many see a move up to 154 pounds as the next logical step for Brook, although Witter believes ‘The Special One’ has earned enough money to warrant a permanent rest.
“The stabbing (Brook was attacked in Tenerife in 2014) could have been the end for him,” Witter pointed out to The Sheffield Star. “A chipped piece of bone (from either of the two eye socket injuries) could have blinded him.
“I don’t know anybody in boxing who has had both eye sockets broken. What’s worrying is that Golovkin is a hard puncher and maybe it’s not perhaps that surprising what damage he did.
“But Spence is not a single, heavy puncher, he doesn’t do it with one punch, it’s more pressure, yet he broke Kell’s socket. Does this suggests there is some kind of (bone) weakness?
“I say he’s been lucky that he hasn’t had worse injuries and I think he should retire because that luck has got to run out. I’m pretty sure his parents and his partner and others in his family are going to say: ‘Right you have had a great career, you’ve been world champion, you’ve done it.’
“He’s earned a ridiculous amount of money and is set for life,” added ‘The Hitter’.
Following surgery, Brook will have a big decision to make on where he goes next as rumours one more fight at 147 against Amir Khan gather pace.
