Tyson Fury goaded Deontay Wilder into a shouting match at the final news conference before their trilogy fight on Sunday.
They meet in Las Vegas this weekend with Fury making the first defence of his WBC world heavyweight title.
Fury told Wilder that Wilder was in denial and he was going to be knocked out.
Fury also told Wilder to retire from boxing as his legacy is in bits.
In response, Wilder says he has nothing to lose.
The much anticipated third fight will be on Sunday and the fight program will begin at around midday.
