After defeating Justin Gaethje in the main event of UFC 254, Khabib Nurmagomedov is now the No. 1 pound-for-pound fighter in the world according to the official UFC ranking. Khabib announced his retirement from MMA after his fight vs Gaethje and shared that he hoped he would leave the sport as the No. 1 pound-for-pound fighter in the world and on Tuesday he learned he met his goal.

With Khabib as the No. 1 fighter - Jon Jones has moved into the No. 2 spot. He dismissed talk about Khabib being the G.O.A.T. earlier this week saying he has fifteen world titles to his four. How did Khabib react to the news and how will Jones answer to the UFC ranking news? Sports Illustrated host Kaitlin O'Toole is joined by SI's Justin Barrasso for insight.
