Anthony Joshua and Daniel Dubois had to be separated after nearly coming to blows in a tense face-off.
It was announced on Wednesday that the two Brits will fight for the IBF heavyweight world title at Wembley Stadium on September 21.
Joshuas promoter Eddie Hearn revealed after that the 34-year-old threatened to smash a chair when the pair nearly clashed during a pre-fight interview, with the footage now released.
Joshua first said Honestly speaking from the bottom of my heart, aside from belts and aside from it being him, Im just ready to fight.
Lets go, lets go. If he wants to swing go, lets go now, Dubois replied but his fellow Brit clapped back Shut up. Relax, relax.
