UFC 253 on Saturday features one of the best main events of the year in Israel Adesanya vs. Paulo Costa. The historic middleweight title fight promises fireworks and is enough to make it one of the biggest pay-per-view events on the calendar.
That isn't the only reason to tune in, though. The light heavyweight division will officially move beyond the Jon Jones era when Dominick Reyes and Jan Blachowicz scrap to crown a new champion after Bones vacated his title to move up to the heavyweight division.
It is a significant night for both divisions. The main event will mark the first time two undefeated fighters have fought for the middleweight belt.
