Two title fights will top the bill at UFC 275 this weekend, with a rematch of an instant classic also set for the card in Singapore.
In the main event, 42-year-old Glover Teixeira (33-7) makes his first defence of the light heavyweight gold, as the second-oldest champion in UFC history takes on Jiri Prochazka (28-3-1). The Czech challenger has surged to a title shot but, at 29, is already vastly experienced and has held belts in other promotions.
