Evander Holyfield and Vitor Belfort came face-to-face ahead of their fight and there was a surprise caller to the press conference.
The two veterans will clash in the ring on Saturday night in Florida as Holyfield, 58, fights for the first time since 2011.
Belfort, a former UFC champion, was due to fight Oscar De La Hoya before the boxing legend was hospitalised with coronavirus.
Holyfield then stepped in at the last minute on a card that also sees Anderson Silva fight Tito Ortiz and David Haye take on Joe Fournier.
If that wasn’t crazy enough, former US President Donald Trump will be on hand to give a ‘no holds barred’ commentary on the fight.
And when Trump phoned the press conference on Thursday night, he was asked who he would like to fight if he was in the ring on 11 September.
He said he’d pass on the chance of taking on a professional boxer and would stick to someone in his world.
“If you said if I had to box somebody, I think my easiest fight would be [current US president] Joe Biden. I think he’d go down very, very quickly.
“He once said ‘oh, I’d like to take him behind the bar’. He’d be in big trouble if he ever did.
“I think Biden would go down within the first few seconds.”
The response left Holyfield and the others on stage laughing.
Biden was the man to beat Trump in the US Presidential elections last November.
Trump controversially refused to accept the result and this led to disorder at the Capitol as his supporters stormed the building where Congress was certifying Biden’s victory.
