Joseph Parker has put forward the idea of fighting Derek Chisora in a trilogy match-up on the undercard of Oleksandr Usyk's and Daniel Dubois' undisputed heavyweight world title clash on July 19 at Wembley Stadium. Now Zealander Parker hasn't fought since a second-round KO of Martin Bakole in February, when he was originally supposed to fight Dubois for the Brit's IBF title.
