There is a lot at stake for Tom Aspinall this weekend, as the Briton defends the undisputed UFC heavyweight title for the first time.

In the main event of UFC 321 in Abu Dhabi, the Wigan fighter defends the gold against France's Ciryl Gane, having been elevated from interim champion when Jon Jones retired this summer. That moment brought an end to a frustrating saga, in which Jones, 38, refused to defend the regular belt against Aspinall, despite the 32-year-old being the rightful next challenger.

Amid that saga, Aspinall in fact took the rare decision to defend the interim belt, knocking out Curtis Blaydes in the first round in Manchester, but he has not fought since that night in July 2024. Now, he takes on Gane, a fellow ex-interim champion, who has twice failed to win the undisputed strap.

In his previous undisputed-title fights, 35-year-old Gane was outpointed by former teammate Francis Ngannou in 2022, and submitted by Jones in round one in 2023. He will enter the Etihad Arena this weekend on the back of a controversial win last time out, having narrowly outpointed Alexander Volkov in December.
