Years later, Frank Mir realizes how horribly underpaid he was for his UFC 100 fight with Brock Lesnar

Frank Mir headlined one of the highest-grossing events in UFC history and was left with little to show for it.

Emanating from the Mandalay Bay Events Center on July 11, 2009, the promotion delivered its first centennial event, UFC 100, featuring a blockbuster heavyweight championship main event pitting division staple Frank Mir against WWE Superstar turned MMA fighter Brock Lesnar. Selling 1.6 million pay-per-views, it was the biggest event in UFC history at the time and still holds strong as the promotions’ fifth biggest seller.
