The Buffalo Bills suffered an agonizing defeat to the Kansas City Chiefs in the AFC Championship game - costing Dave Portnoy a fortune.
Before the Bills faced the Chiefs at Arrowhead on Sunday night, the Barstool Sports founder revealed he had placed a staggering $1million on Buffalo to win the Super Bowl this season.
He wrote on X: 'Here is a 3 team parlay for today. But I gotta be honest. My only focus is the Bills winning today cause I got a milly on them to win the Super Bowl.'
Unfortunately for Portnoy, Josh Allen was unable to inspire the Bills to their first Super Bowl appearance since 1994 after slumping to a dramatic 32-29 loss in Kansas City.
At the start of the fourth quarter the 47-year-old was left seething when Buffalo was controversially deemed to have missed out on a crucial first down, accusing NFL referees of 'cheating' to help Kansas City.
He shared a photo of the moment in the game and said: 'Insane. #nflrigged'.

However, while taking aim at the officials once again, in an angry video message Portnoy also hit out at Bills head coach Sean McDermott for running a tush push 'without the push' in the first place.
'Guts ripped out, I feel for all of Buffalo,' he said. 'Let me tell you something: the refs should be in f***ing prison. Refs should be in prison, that fourth-down spot changed the whole game.
'McDermott should be in prison, the Bills coach. That tush push that they run, that they kept running that doesn't work... yeah the refs f***ed you, [but] do they not know what a tush push is? You put two f***ing huge guys in and you push! They don't do that.
'I thought Dalton Kincaid should've caught that pass, but whatever. You have the ball, down three, and you couldn't have asked for more.
'Yeah the refs f***ed you, yeah the tush push [was] absolutely the dumbest. I can't get over doing a tush push without the push.'
While it was heartbreak for Portnoy and the Bills, the Chiefs are now just one win away from becoming the first team in NFL history to win three consecutive Super Bowls.
Travis Kelce will take on his brother Jason's beloved Philadelphia Eagles in New Orleans on February 9 after beating Josh Allen and Buffalo again.

An emotional Taylor Swift planted a kiss on Kelce as they celebrated the Chiefs securing their spot in the Super Bowl on Sunday night.
Swift, who looked teary as she made her way down to the field to find her boyfriend, celebrated with his mom Donna at the end of the pulsating 32-29 win.
The 14-time Grammy Award-winning superstar then stood and watched Kelce get interviewed on CBS with Brittany Mahomes as ticker tape rained down from above.
Swift was smiling and nodding in approval as Kelce shouted: 'Never satisfied, baby!' and then sang a line from 'Get Down Tonight' by KC and The Sunshine Band.
