Elsewhere on the main card, Ballymena's Rhys McKee lost to France's Axel Sola in the third round.
In a back-and-forth contest, Sola dropped McKee with a body shot, before the referee stopped the contest on the ground.
McKee protested the stoppage after seeming to recover quickly, but the defeat leaves the 29-year-old with five defeats from six UFC fights.
It was a bitter blow for the welterweight, whose momentum has been halted once more after earning his first UFC win against Daniel Frunza in April.
On the undercard, Britain's Sam Patterson continued the impressive start to his UFC career as a flurry of punches stopped American Trey Waters in the first round.
The victory was Patterson's fourth consecutive first-round finish which is the current longest streak in the UFC.
Fellow Briton Harry Hardwick suffered defeat, however, as a series of leg kicks from Kaue Fernandes left the 30-year-old unable to continue.
Hardwick, who is the Cage Warriors featherweight champion, was making his UFC debut and took the bout at only five days' notice.
There was also defeat for Ireland's Shauna Bannon as she submitted to a rear-naked choke by Sam Hughes in the second round of their strawweight contest.
