UFC 231 featured two title tilts and both fighters who walked out with the belts put on fantastic performances.
In the main event, Max Holloway turned it on against Brian Ortega. Holloway peppered Ortega throughout and forced the doctor to halt the bout before the fifth and final frame. Ortega wasn't outclassed, but he simply could not keep the pace of the champion.
Valentina Shevchenko was thought to be the uncrowned flyweight champ, but in Toronto she grabbed the crown with a dominant performance over Joanna Jedrzejczyk.
The champions now move into 2019 with divisions hot on their heels.
