UFC 275 full results: Prochazka submits Teixeira; Shevchenko ekes by Santos

In just his third fight in the UFC, knockout artist Jiri Prochazka surprised Glover Teixeira and those in attendance Saturday at Singapore Indoor Stadium with a fifth-round submission to win the light heavyweight title.

Teixeira, 42, became the oldest fighter to win a UFC title when he submitted Jan Blachowicz at UFC 262 in October and shook up the light heavyweight division. His title reign ends with zero successful defenses after Prochazka's submission.

In the co-main event, flyweight champion Valentina Shevchenko narrowly won a split decision over Taila Santos.
