Forget a bottle, get Alex Volkanovski a shoe ... 'cause that's what the UFC star was chuggin' champagne out of at the Raiders game, celebrating his win over Brian Ortega.
And, we got it all on video!
The 32-year-old Aussie fighter hit up the Dolphins vs. Raiders game on Sunday -- after his crazy unanimous decision victory the night before at UFC 266 -- and the football game was LIT!
Check out this clip ... you can clearly see AV enjoyin' himself in Allegiant Stadium's end zone nightclub, watching the game with his UFC belt and a crowd of people.
