Everything you need to know about UFC 275: Glover Teixeira vs. Jiri Prochazka

UFC 275 has a topsy-turvy appeal to it.

Two former strawweight champions, Zhang Weili and Joanna Jedrzejczyk, meet in a rematch of the 2020 fight of the year, a relentless back-and-forth that was one of the greatest fights in UFC history.

And that's not the main event. It's not even the co-main.

The headliner of Saturday's pay-per-view event in Singapore is a light heavyweight title bout between Glover Teixeira, the 42-year-old new champion, and challenger Jiri Prochazka. And the co-main event is also a title bout, in which perhaps the most dominant champ in the UFC, flyweight Valentina Shevchenko, defends against 19-1 Taila Santos.

Two titles are on the line at UFC 275. Glover Teixeira defends his light heavyweight championship against fast-rising Jiri Prochazka, and Valentina Shevchenko aims to keep her flyweight dominance going when she faces Taila Santos. Plus, strawweights Zhang Weili and Joanna Jedrzejczyk meet in a rematch of the 2020 fight of the year.
