Murat Gassiev offers Derek Chisora shot at his WBA heavyweight title, if he beats Deontay Wilder

Murat Gassiev would welcome a fight with Derek Chisora or Deontay Wilder.

Gassiev holds a WBA 'regular' heavyweight title while Oleksandr Usyk, who beat the Russian in their 2018 cruiserweight clash, is that sanctioning body's 'super' or primary world heavyweight champion.
