UFC 165 – September 21, 2013 (Watch on UFC FIGHT PASS)
That six-fight winning streak earned Gustafsson a shot at UFC light heavyweight champion Jon Jones, and while the Swede clearly deserved that fight, he was a significant underdog to a fighter who had just run through Rua, Rampage Jackson, Lyoto Machida, Rashad Evans, Vitor Belfort and Chael Sonnen in succession. But when the Octagon door closed, Gustafsson gave Jones hell, and though Jones emerged victorious via decision, the two had produced one of the greatest fights in UFC history, establishing Gustafsson’s reputation as one of the best in the game in the process.
