We look at the opening betting odds for the main event of the UFC 321 fight card, the UFC heavyweight title fight between champion Tom Aspinall and Ciryl Gane.

Tom Aspinall will look to officially begin his undisputed heavyweight title reign in the UFC 321 main event when he clashes with former interim titleholder Ciryl Gane.

Aspinall, meanwhile, has looked near-unstoppable during his supersonic rise to the top, knocking out highly-rated Sergei Pavlovich to win interim gold before avenging his freak injury loss to Curtis Blaydes - his only title defence while he played the waiting game for Jones.
