The former world champ and Sky Sports pundit also faced homelessness when his battle to clear his name wiped out his life savings.
Three waitresses alleged he touched their arms in a sexual manner at a dinner before the Anthony Joshua v Oleksandr Usyk world heavyweight title bout at the Tottenham Hotspur Stadium in September 2021.
McCrory, 59, denied any sexual motive and insisted he was only trying to get their attention.
He was cleared of all charges in just 90 minutes last September at Wood Green crown court, North London.
And he has now teamed up with homeless charity CEO Sleepout to raise awareness of the plight facing record numbers in the UK.
Since 2010, rough sleeping has rocketed by 74 per cent and the charity stages annual sleepouts for business leaders to raise funds and awareness.
This year’s fundraising drive is being kicked off with an event at Newcastle United’s stadium St James’ Park on March 21.
Ex-cruiserweight Glenn, of Newcastle, said: “I know what it is like to hit rock bottom as I lost everything.
“I was in the hands of the crisis team and my weight plummeted.
“Everything fell apart.
“To not know what your future holds or where your next meal is coming from is absolutely terrifying.
“People see those in the public eye and think they must have a great life, but anyone can have their world pulled from under them in a heartbeat – and I’m living proof.
“You could lose your job, savings or family – or just become unwell – and the downward spiral starts.”
Sleepout boss Bianca Robinson said: “Glenn’s story is heartbreaking but it is a stark reminder that everyone can be just a few steps away from being made homeless.”
