The fighters have made weight as UFC 327 arrives in Miami. The main event will decide who becomes the new UFC light heavyweight champion: Jiri Prochazka or Carlos Ulberg.
Weigh-ins and schedule
All fighters took part in the official weigh-ins in Miami the day before the event. The UFC ran a Morning Weigh-In show and a Ceremonial Weigh-In for fans. The Morning Weigh-In show began at 8:50 a.m. ET / 5:50 a.m. PT. The Ceremonial Weigh-In started at 5:00 p.m. ET / 2:00 p.m. PT.
Main event background
Jiri Prochazka and Carlos Ulberg were chosen to fight for the vacant light heavyweight title. Alex Pereira gave up the belt as he moves up to heavyweight. Pereira will fight Ciryl Gane for the interim UFC heavyweight title at UFC Freedom 250 in about two months.
Prochazka first became light heavyweight champion when he beat Glover Teixeira at UFC 275. He then had to vacate the belt because of an injury before he could defend it. Since joining the UFC in 2020 from RIZIN, where he was also a champion, Prochazka has a 6-2 UFC record. He tried twice to win the title back but lost to Alex Pereira at UFC 295 and again at UFC 303.
Ulberg’s rise and recent form
Carlos Ulberg is on a long winning run. He has won nine straight fights since losing his UFC debut to Kennedy Nzechukwu. That loss is the only defeat in his mixed martial arts career so far.
Ulberg’s last three opponents were all former champions or top title challengers. He earned decision wins over Volkan Oezdemir and Jan Blachowicz, and he knocked out Dominick Reyes in his most recent outing.
What to watch on fight night
This title bout will test Prochazka’s resilience and Ulberg’s momentum. Prochazka brings big-name experience and past championship history. Ulberg brings confidence from a long win streak and recent wins over high-level opponents.
Expect fireworks as both men have heavy striking and finishing ability. The winner will leave Miami as the new UFC light heavyweight champion.
