UFC 321 takes place at Etihad Arena in Abu Dhabi, featuring two title fights: Tom Aspinall vs. Ciryl Gane for the heavyweight title and Mackenzie Dern vs. Virna Jandiroba for the vacant women's strawweight title.

In a move that reshaped the women’s strawweight division, the division’s longtime champion Zhang Weili vacated the 115-pound title back in August. She did so

Now a full year removed from her last fight, former two-division PFL Champion Larissa Pacheco is officially a free agent.

Arguably the greatest fighter to never step foot in the UFC Octagon, Fedor Emelianenko had a legendary 48-fight pro MMA career with wins over Andrei Arlovski, Tim Sylvia, Mark Coleman, Kevin Randleman and more.

This came full circle for Mackenzie Dern in her last trip to the octagon.

History was made in multiple ways at UFC Vancouver, but none more significant than Drew Dober breaking Dustin Poirier's knockout record.

In fact, the one-sided mauling was so bad that two months after UFC 121, Pro Wrestling Observer’s Dave Meltzer revealed that not only was Lesnar ignoring phone calls from the promotion, he was even reconsidering his continued participation in MMA.

Gane failed to capture the title when he lost a decision to Francis Ngannou in 2022 and again when he was quickly submitted by Jones in 2023. Those are the only losses in Gane's career, and he now looks to make good on his third opportunity at gold when he faces Aspinall.
