UFC Fight Pass 500 moments video: Conor McGregor walks out to Sinead O’Connor

The UFC recently held its 500th live event, and the organization is marking the occasion with a list of 500 unforgettable moments.

UFC 244 marked the promotion’s 500th live event, and the organization is marking the occasion with “an internally curated list of 500 Unforgettable Moments from UFC history.”

Scheduled to be released in seven installments, UFC Fight Pass 500 Moments shines a spotlight on some of the most memorable highlights – and lowlights – from the UFC’s 26-year run, both in and out of the cage.

UFC Fight Pass officials have committed to sharing video of a few of those key moments with MMA Junkie, as well. This time, we bring you one of the most memorable nights in MMA history, UFC 194 on July 11, 2015 in Las Vegas.

The MGM Grand Garden Arena was already abuzz after Robbie Lawler finished Rory MacDonald to retain the welterweight title in a bout name-checked by many as the greatest in UFC history.

Then came the walkout for the main event, when a heavily Irish crowd was treated to legendary singer Sinead O’Connor’s live performance for [autotag]Conor McGregor[/autotag]’s walkout. He then went out and finished [autotag]Chad Mendes[/autotag] in the second round to claim the interim featherweight belt.
