2019 has been a wild ride for the sport of MMA. The UFC kicked off a new era with its partnership with ESPN, ONE Championship has arrived as an international player and Bellator has chimed in with some of the most exciting fights and fighters of the first six months.
The UFC has crowned six new champions. Jon Jones is back as the defending light heavyweight king. Patricio Pitbull avenged his brother with a knockout win over Michael Chandler. Conor McGregor and Khabib Nurmagomedov were finally punished for their wild post-fight brawl (h/t ESPN.com's Brett Okamoto & Ariel Helwani).
