Max Holloway dominated Brian Ortega to earn a fourth-round TKO stoppage to defend his featherweight title at UFC 231 on Saturday.

Holloway (20-3), in action for the first time in more than a year, was impressive against the gutsy Ortega, before a doctor's stoppage ended the bout in Toronto.

Ortega showed plenty of heart, but it seemed only a matter of time before Holloway would secure his victory.

Holloway landed multiple blows to Ortega's face and it appeared that all the damage caused to the latter's eye led to the stoppage.

Earlier, Valentina Shevchenko claimed the vacant women's flyweight championship with a unanimous-decision win over Joanna Jedrzejczyk.

Hakeem Dawodu enjoyed a split-decision win over Kyle Bochniak in their featherweight contest, while Thiago Santos knocked out Jimi Manuwa in the second round of their fight.
