15. Matt Brown – 2016
‘The Immortal’ was a big fan favorite in his fighting prime. However, he learned the hard way that it’s a bad idea to mess with Brazilian fans. They are one of the most passionate MMA nations in the world. Fighters discover how partisan they are when they travel to the South American nation. Brown made a mistake by flipping off the fans at a weigh-in in Curitiba.

Brown was eating his breakfast in the hotel when somebody assaulted him from behind. They sucker-punched him in the back of his head and ran off. Meanwhile, he experienced bottles being thrown at him and a lot of boos. The welterweight isn’t the first fighter to suffer the wrath of Brazil, but his ordeal was worse than most.
