LAS VEGAS -- The most anticipated UFC fight of the year ended with an anticlimactic finish Saturday night as Dustin Poirier captured his trilogy fight with Conor McGregor, who suffered an ankle injury at the end of the first round and couldn't continue.
Poirier stopped McGregor at UFC 257 in January via a second-round TKO. In 2014 at UFC 178, McGregor knocked out Poirier in under two minutes.
UFC president Dana White has said Saturday's winner will fight for the UFC lightweight title next against champion Charles Oliveira.
