UFC 321 went down yesterday (Sat., Oct. 25, 2025) from inside Etihad Arena in Abu Dhabi, United Arab Emirates which saw the Heavyweight main event title fight end in anti-climactic fashion after Ciryl Gane inadvertently poked Tom Aspinall in the eye,

UFC 321 unfolded inside Abu Dhabi’s Etihad Arena with all the weight of anticipation surrounding the heavyweight division. What was expected to be a heavyweight showcase ended abruptly when Tom Aspinall (15-3) and Ciryl Gane (12-3) saw their title bout ruled a no contest.

Mackenzie Dern is among the most credentialed grapplers to claim UFC gold, having become an ADCC and no gi BJJ (black belt) world champion en route to achieving the No. 1 IBJJF ranking before transitioning to MMA. Next, the strawweight queen could be set for a challenge from one of the division’s top wrestlers.

In the UFC 321 co-main event Saturday, Dern (16-5 MMA, 11-5 UFC) defeated Virna Jandiroba by unanimous decision (48-47, 48-47, 49-46) to claim ownership to the vacant 115-pound title. The bout took place at Etihad Arena on Yas Island, Abu Dhabi.

Analysis of UFC 321's biggest storylines, and why Tom Aspinall made the right call taking a no contest title defense.

The UFC Fight Night headlined by Dvalishvili’s dominant win over Petr Yan in 2023 broke the record for most takedowns landed at an event with 59. ‘The Machine’ contributed massively to that record with 11 at the Russian’s expense.

Virna Jandiroba lost for the first time in four years and now will have to work her way back to title contention at 115 pounds.

Mackenzie Dern "did a little bit of everything" on her way to winning the vacant UFC women's strawweight title with a unanimous decision over Virna Jandiroba at UFC 321.
