The UFC is moving toward officially booking Dustin Poirier vs. Conor McGregor III for later this year.

According to multiple sources, the trilogy is "close" to being finalized for UFC 264 on July 10. It is not signed yet or fully agreed to, but there is optimism that it could be finalized as soon as this week, sources say.

Poirier defeated McGregor in January via second-round TKO in a rematch of their 2014 fight. Back then, at UFC 178, McGregor defeated Poirier via first-round TKO.

The trilogy, which is expected to be one of the most lucrative in UFC history, is slated to serve as a five-round main event at 155 pounds, just like the rematch was. The original fight took place at 145 pounds.

McGregor (22-5) would be looking to secure his first win since January 2020, while Poirier (27-6, 1 NC) will hope to extend his winning streak to three in a row.

The location for the event hasn't been announced, though it is expected to be open to fans, sources say.

UFC president Dana White said Saturday that the plan is for UFC 264 to be at T-Mobile Arena in Las Vegas, and when asked if Poirier vs. McGregor would be the main event, he said: "I hope so. We all hope so."
