The former two-division champ closed out the night at T-Mobile Arena with a performance as emphatic as it was brilliant, setting in motion a TKO of Donald Cerrone with a flurry of shoulder strikes. A head kick sent the man responsible for the most head-kick knockout wins in octagon history to the canvas, and McGregor finished the job with 40 seconds on the clock.
Main card attraction Oleinik picked up his fifth bonus for a submission win over Maurice Greene. The Russian vet couldn’t finish the American with a scarf hold in the first frame, but he kept on the pressure until he found an armbar that marked his sixth UFC finish by submission.
Kelleher, a last-second addition to the pay-per-view fights, taught Dana White Contender Series vet Ode Osbourne a lesson on the mat, cinching a first-round guillotine that started the UFC newcomer off on the wrong foot.
Submission specialist Ferreira added another submission to the night against ex-champ Anthony Pettis. In his biggest win to date, he picked up his third fight-night bonus with a rear-naked choke, his second such UFC win.
The announced attendance was 19,040 for a live gate of $11,089,129.30, which makes it the second-biggest MMA event in history in the state of Nevada.
