More than four years after announcing his retirement, Brook (40-3, 28 KOs) has shared a surprise update, stating that he's ready to return to the ring at the age of 40.

"I'm telling you something here and now, some massive news is about to drop," Brook told talkSPORT. "I'm coming back. There is big news of a massive fight coming your way. Back in the professional ring, British Boxing Board of Control, coming out of retirement.

"I can't give anyone a clue over the opponent, but we won't be waiting much longer. It'll happen this year, it's about done. And we will be giving the fans another massive fight. I'll return at middleweight or super middleweight, around those divisions."

The Sheffield native remained cryptic when asked if the opponent could be Chris Eubank Jr saying, "Who knows?'

"Special K" Brook was an IBF welterweight titleholder from 2014 to 2017, a belt he first landed by beating Shawn Porter by majority decision.

In 2016, while holding the 147-pound crown, Brook stepped up to middleweight to challenge Gennadiy Golovkin, but suffered a fractured eye socket and was stopped in five rounds.

He didn't fare much better in his next bout, suffering an 11th-round stoppage against Errol Spence in defense of his title on home soil.

Following the Spence fight, Brook strung three wins together to set himself up for another welterweight title shot, this time against Terence Crawford in November 2020, only to get stopped inside four rounds.

Brook last fought on February 19, 2022, and stopped Amir Khan in six rounds.
