Conor McGregor, Dustin Poirier set to meet at UFC 178 in Las Vegas

The one thing that was guaranteed after a massive crowd turned out for Conor McGregor Saturday in Dublin, Ireland, following weeks of frequently over-the-top trash talking that everybody and his brother would want to fight him if he won.

McGregor stopped Diego Brandao in the first round and, predictably, heard a lot of fighters calling his name.

Dustin Poirier, though, is the one who will get the call. The UFC announced the bout Tuesday on its Twitter page. It will occur at UFC 178 in Las Vegas, where Jon Jones will defend his light heavyweight title in the main event against Alexander Gustafsson.

The Jones-Gustafsson bout is a rematch of one of the greatest in UFC history, and one that had a close and somewhat disputed ending.

But with McGregor's ability to talk, his fight with Poirier won't be overlooked, that's for certain. Seconds after the fight was official, McGregor alluded to his abiity to draw a crowd on his Twitter page.

Unquestionably, McGregor is a fighter on the rise and will attract some fans to the Las Vegas show. How big he'll go over outside of Ireland remains to be seen.

McGregor is now 3-0 in the UFC, with wins over Brandao, Max Holloway and Marcus Brimage. On Monday, voting media members ranked him 10th in the featherweight division. Poirier, though, is ranked sixth and on a three-fight winning streak.

Poirier, who is 16-3 overall, last lost to Cub Swanson in 2013.
