An ultimatum has paid off for Joseph Parker and his team ahead of his heavyweight boxing match against Dereck Chisora

The pair will fight at London's O2 Arena on October 26th, UK time.

Talks had threatened to break down between the two parties, with Chisora's ongoing refusal to allow for random drug testing in the build up and following the fight.

But Parker's manager David Higgins says they were prepared to walk away from the fight.
