Usman Nurmagomedov delivers a devastating first-round knockout and remains undefeated

Usman Nurmagomedov just sent another reminder to the MMA world that he’s one of the most dangerous fighters on the planet. A devastating first-round knockout, another successful title defense, and his undefeated record remains untouched after putting Archie Colgan away in emphatic fashion. If this really was his final PFL appearance, he couldn’t have scripted a better ending. He walked out with another statement victory and left fans wondering what could possibly be next. At this point, the list of fighters capable of stopping Usman seems to be getting shorter and shorter.
