UFC 321 is scheduled to take place on October 25, 2025, at the Etihad Arena in Abu Dhabi (Yas Island). The main event features Tom Aspinall defending the UFC Heavyweight Championship against Ciryl Gane, with a co-main event for the vacant UFC Women's Strawweight Championship between Virna Jandiroba and Mackenzie Dern. The main card starts at 2:00 p.m. ET, with preliminary bouts beginning earlier in the day. The event will be available on ESPN+ PPV, following the early prelims and prelims broadcast.
