90-year-old Don King gives utterly bizarre 30-minute press conference speech ahead of Daniel Dubois v Trevor Bryan as promoter who represented Mike Tyson and Muhammad Ali talks politics

At 90 years of age, Don King is still promoting boxing.

The highly controversial figure first came to prominence in the sport back in 1974, with the legendary 'Rumble in the Jungle' between Muhammad Ali and George Foreman being his first major event.

48 years on, King's endured his fair share of scandals having been sued by several boxers - most famously Mike Tyson - with many of them alleging that he defrauded them.

Remarkably though, at 90, he is still involved in the sport and set to stage a show this weekend.

King now promotes American heavyweight Trevor Bryan, who holds the lesser WBA 'regular' belt in the division.

Oleksandr Usyk is the true WBA heavyweight champion, but the 'regular' belt could become a pathway to a shot at the Ukrainian in future.

On Saturday night, Bryan is set to defend it against Britain's Daniel Dubois.

Unexpectedly, King outbid Dubois' promoter Frank Warren and won the rights to stage the fight.
