Got a call to fight former UFC light heavyweight champ Jan Blachowicz on less than two weeks’ notice? Navajo Stirling said yes—and turned it into a career-making win. He dropped Blachowicz with a massive early left hand, then finished him with elbows for a Round 1 TKO at 2:56. Still undefeated (11-0, 6-0 UFC), Stirling showed respect to the 43-year-old post-fight, then hilariously called out Khalil Rountree or Paulo Costa for a year-end bout: “1-800-I'm-Going-to-Whip-That-Ass.” Who do you think he should fight next to keep his title momentum?
