UFC 191 now has its main event, and it's a rematch in the flyweight division. During the UFC Fight Night: Duffee vs. Mir broadcast, it was announced that reigning champion Demetrious Johnson will take on John Dodson on September 5th at the MGM Grand in Las Vegas. The two previously met in January 2013 at UFC on FOX 6 in Chicago, with Mighty Mouse winning a thrilling unanimous decision after suffering two early knockdowns.
Johnson (22-2-1) has been on an absolute tear since his close call vs. Dodson. Four of his last five title defenses have ended in a finish, including his armbar of Kyoji Horiguchi with literally just 1 second left in the 5th round of a fight he was going to win 50-45 anyway. Unless the UFC starts implementing 7 round fights, 4:59 of round 5 is the latest stoppage you'll ever see in a title fight or main event. His prolonged dominance as the UFC's only flyweight champion has put him in the discussion as perhaps the best fighter in the world.
Dodson (17-6) has won 3 straight and has only been bested by Johnson inside the Octagon. The 30-year-old knocked out Darrell Montague, stopped John Moraga, but then tore his ACL and was sidelined for nearly a full year. When he returned to action against Zach Makovsky at UFC 187, his performance was sub-standard and he was quite fortunate to get a unanimous decision win. Evidently though, the UFC has seen him as the man best suited (or most available) to be Johnson's next title defense.
Also on the card are light heavyweights Anthony Johnson and Jan Blachowicz, bantamweights Francisco Rivera and John Lineker, plus women's strawweights Paige VanZant and Alex Chambers.
