Glover Teixeira is going on the defensive…

The 42-year-old Brazilian mixed martial artist and UFC light heavyweight champion will defend his title against Jiri Prochazka on May 7, according to ESPN sources.

Both Teixeira and Prochazka have committed to the date and opponent.

The 205-pound title fight will take place on a UFC 274 pay-per-view event. The UFC has not announced an official venue for the event.

Teixeira (33-7) capped off an improbable run to the UFC title in October, when he submitted Jan Blachowicz at UFC 267 to capture a belt at age 42. The victory came more than seven years after Teixeira came up short in his first title bid against Jon Jones in 2014. 

Originally from Brazil, now fighting out of Connecticut, Teixeira has won six in a row, including finishes of Blachowicz, Thiago Santos and Anthony Smith.

Prochazka (28-3-1) has been a dark horse in the 205-pound division ever since signing with the UFC in 2020. He’s fought only twice inside the Octagon, but he’s been supremely impressive in finishes of Volkan Oezdemir and Dominick Reyes.

Prochazka, of Czech Republic, has recorded 10 consecutive knockout finishes.
