MMA divisional rankings: Upset KO boosts Song Yadong at bantamweight

Song Yadong scored the biggest victory of his career on Saturday at UFC Fight Night in Shanghai, knocking out onetime men's bantamweight title challenger Umar Nurmagomedov . The stunning second-round finish as a nearly 5-1 underdog propelled Song up three spots into the top four in the ESPN divisional rankings. Nurmagomedov, who previously owned the No. 4 position at 135-pounds, slips down one spot, as do the other two fighters who had been ranked ahead of Song, Mario Bautista and Cory Sandhagen . That was this week's only movement in the divisional rankings. Here are the ESPN pound-for-pound MMA rankings and a list of current UFC champions in all weight classes. Results are current; rankings as of Sept. 1. To be eligible for the rankings, a fighter must have competed over the past 12 months or must have an upcoming fight booked. Fighters who have been dropped for inactivity can be reinstated only after they compete. HEAVYWEIGHT (up to 265 pounds) 1.
