Earlier tonight (Sat. July 6, 2019) at UFC 239 on pay-per-view (PPV), welterweights Ben Askren and Jorge Masvidal met in a highly-anticipated bout.

It only took Masvidal five seconds to end Askren’s undefeated record. “Gamebred” came out knowing Askren would shoot in on him immediately, and threw up a flying knee that connected on the top of Askren’s head, rendering him unconscious for one of the scariest knockouts you’ll ever see in mixed martial arts (MMA).
