After becoming the first person to score a knockdown of the near-perfect champion in the 1st round, Edwards struggled in the following rounds to build any kind of momentum. Usman took the fight with his superior wrestling and heavy punching combinations and looked on his way to another title defense as he closed in on Anderson Silva’s record for most all-time. Usman’s pace slowed in Round 5 but was likely leading to a unanimous decision win for the champion as Edwards looked defeated in his corner as his team begged him to come alive in the final round. Suddenly, Edwards landed a right jab and hit a left head kick that knocked Usman out cold at 4:04 of Round 5. “Pound-for-pound. Headshot. Dead,” Edwards told UFC commentator Joe Rogan during his post-fight interview. “I’ve been saying all week that I feel like this is my moment. Everything that’s happened in the past. The last two years, the pandemic. There’s no ring rust. I told you, now look at me now.” Edwards improved to 20-3 (1 NC) with the win over Usman. His unbeaten streak improved to 11. Usman saw his 19-fight winning streak snapped in the blink of an eye and suffered his first defeat in nine years. It was the fourth-last finish in a championship match — seconds shy of Usman’s own finish of Colby Covington in 2019.
