Warren told Mail Sport in January that he would be willing to make a £1million bet with Hearn that his stable will ultimately emerge victorious on the night.
Speaking earlier this year, Warren said: ‘We've got to sort out the weights. 'Because there's five fights, there will be a winner one of the teams will win unless we get a draw.
'To make it a little bit more spicy, I'd like to have a wager on it with [Hearn] as well. [I'd be willing to bet] a million pounds.'
