Former heavyweight boxing champion Frank Bruno says he wants to return to the ring.
The 54-year-old, who has bi-polar disorder, said he was "coming back into boxing" to help him cope with the effects of his medication.
Asked how drugs had affected him, he told ITV's This Morning: "They made me suicidal - mess up your head, mess up your clock - you can't sleep.
"I'm walking around break-dancing I've got so much energy.
"I feel like superman, I'm going to the gym all the time, working hard - that's why I've got to come into boxing ... to get this out of my system, because I don't want to end up in Broadmoor hospital.
"I'm coming back into boxing," the former WBC heavyweight then repeated.
Asked by co-presenter Phillip Schofield if the move was a good idea he replied: "I haven't got no choice. I train every day.
"I can't really sit down and let these so-called promoters say that their guy beat me in two rounds - and I'm alive and I've got to take that."
Continuing, he said: "It's my job, it's my profession ... you're good at your job, I'm good at my job."
Bruno was recently pictured training in the ring with Ricky Hatton, another former world champion.
Fans reacted to Monday's announcement with trepidation.
TV presenter Paddy McGuinness posted on Twitter: "Back in the day me & my Dad watched all Frank Bruno's fights, we loved him. Hearing he's planning on fighting again makes me sad."
Boxing trainer David Coldwell wrote: "Is this comeback talk tongue in cheek? Please tell me no one would actually 'help' Frank Bruno to fight in the ring again?!
"I don't actually believe any established promoter would put Frank Bruno on one of their shows."
