Jiri Prochazka made history Saturday night -- becoming the first Czech fighter to win a UFC championship -- and thousands of delirious fans showed up to greet the home country hero on Monday.
29-year-old Prochazka was losing his UFC 275 title fight with Glover Teixeira ... but somehow, someway managed to get the 42-year-old champ's neck and force the tap-out with 28 seconds left in the 5-round fight.
The win made Jiri the first Czech-born champ ... and when the newly crowned champ arrived back in his hometown in Brno, there was a huge crowd waiting to give him a hero's welcome!
What's more impressive ... this was only Prochazka's 3rd fight in the UFC. He previously beat Volkan Oezdemir (July 2020) and Dominick Reyes (May 2021).
But, he's been fighting MMA (and other combat forms) for a long time ... going back professionally to 2012. Jiri's overall record is 29-3.
The champ's home, and the party is on!!
