UFC 257: Poirier vs. McGregor 2

Conor McGregor faced old rival Dustin Poirier in the first UFC fight in over six months to allow a live crowd, albeit a limited one. Eight years in the making, Poirier shocked the world by becoming the first man to TKO McGregor in MMA, setting up their trilogy at UFC 264. Michael Chandler also announced himself in the UFC with a blistering performance over Dan Hooker, who had spent 90 days separated from his family in order to compete due to New Zealand travel restrictions.
