Kell Brook, a former world welterweight champion, has revealed he is having trouble with retirement and is looking for mental health treatment.

He made these remarks in response to a Sun tabloid video that appeared to show him snorting white powder at a party.

After 40 victories from 43 professional fights, Brook, 36, announced his retirement from boxing in May.

“I screwed up. I put my hands in the air,” Brook tweeted.

According to his manager Terry Thompson, Brook was “having a laugh” in the video, which was “a joke,” according to the Sun.

Brook stated to the Telegraph last year that he had “nothing left to prove” and that his “heart was no longer in it” as reasons for quitting the sport.

He said, “I battle with mental health and I’m finding retirement incredibly hard. It’s no secret.

“I’m actively looking for the assistance I require to set myself on the proper course. I apologize once more for whatever harm I may have caused.

From 2014 through 2017, Brook held the IBF world championship after defeating American Shawn Porter in California to win the belt.

He earlier claimed that after losing his title in a match against Errol Spence, during which he damaged his eye socket for the second time, he sought the services of a counselor to help him deal with sadness.

Twelve months prior, Brook defeated fierce rival Amir Khan in the sixth round. However, in January, Liam Smith declared that fighting the Sheffield fighter was an option following his victory over Chris Eubank Jr.
