The event is will broadcast from the UFC Fight Island facilities in Abu Dhabi.
The UFC 257 live stream is here, and it's headlined by Conor McGregor's return to the ring for Poirier vs McGregor 2. The last time they fought, at UFC 178 back in September 2014, McGregor ended things early with a round 1 TKO.
Despite that result, McGregor isn't seen to repeat that quick dusting this time. Poirier's loss at UFC 178 wound up being his last featherweight division matchup, and he would advance up the weight classifications to the 155-pound Lightweight division — where he's thrived since.

This is only McGregor's third time competing at lightweight in his UFC career. He won the division title in 2016 by knocking out Eddie Alvarez, and lost it in his next defense against Khabib Nurmagomedov.
At the UFC 257 press conference on Thursday morning, McGregor and Poirier answered questions from the media and then had an intense — yet also pleasant and professional — staredown. If there's any animosity between the two, it's not as big a priority for them as making money.
Most experts online are picking McGregor, and bookies have him winning as well. DraftKings, last we checked, has McGregor at the moneyline favorite at -305 to Poirier's +250.
This is McGregor's first fight in over a year, as his last trip inside the octagon was a welterweight clash that saw him defeat Donald Cerrone on Jan. 18 in a first round TKO. His previous fight saw him lose to the since-retired Nurmagomedov in October 2018, who took him 4 rounds and won via neck crank submission.
While Nurmagomedov declared he would retire, he is still the champion. And because UFC president Dana White is a consummate promoter, he's teased the possibility of Khabib returning if any of the top four lightweights on the card (McGregor, Poirier, Michael Chandler and Dan Hooker) has a strong enough showing to tempt him to come back.
Either way, this match is expected to give us a clear sign for who will be challenging for the Lightweight Championship, since Justin Gaethje is merely the top-ranked interim title holder.
The UFC 257 live stream undercard has just been changed. UFC removed Ottman Azaitar from the card, after violating the promotion's health and safety protocols by bringing an unauthorized guest to Fight Island.
Matt Frevola, who Azaitar was scheduled to face, is now moved to the main prelims, which he will headline against Arman Tsarukyan. Tsarukyan's opponent, Nasrat Haqparast, was removed due to illness.
