Boxing authorities should fund a new foundation to help fighters with mental health issues, says Barry McGuigan.
The former world featherweight champion, 55, wants the new body to pay for treatment where needed.
World heavyweight champion Tyson Fury has revealed he is suffering from depression and has taken cocaine to help him deal with the issue.
“It should happen sooner rather than later because we don’t want a fatality on our hands,” said McGuigan.
He told BBC Radio 5 live the sport has “been blind” to elite athletes suffering mental illness, adding he is “genuinely concerned” about Fury.
The unbeaten Briton faces losing his licence after admitting to Rolling Stone magazine he has taken cocaine.
Fury reportedly pulled out of his rematch with Wladimir Klitschko on 29 October because of mental health issues.
On Monday, he tweeted to say boxing was the “saddest thing” he had taken part in and suggested he was retiring from the sport, before retracting his decision a few hours later.
