Dustin Poirier will come face-to-face with Conor McGregor for the final time at the UFC 264 ceremonial weigh-ins on Friday evening - and we've got you covered with a live stream of all the action from Las Vegas.

The first hint of the drama to come at the weekend will happen a little earlier in the afternoon though with both men needing to hit the scales at 156lb to make the contest official.

Adam Catterall and Nick Peet will be joined by former UFC middleweight champion Michael Bisping from 4.45pm for the Live Weigh-In Show, looking forward to the weekend's card as they run the rule over the athletes hitting the scales at the official weigh ins.

A live stream of the Weigh In Show will be embedded at the top of this article, with a live stream of the ceremonial weigh-ins embedded just below, so bookmark this page to return to throughout Friday!

Neither Poirier nor McGregor have a history of missing weight although the two athletes are known to endure fairly uncomfortable cuts in order to make the scales. 

After a couple of hours rest and recuperation to rehydrate, the two will return to the stage one last time before their epic trilogy fight to face-off for the cameras at the ceremonial weigh-ins.

We'll bring you live stream coverage of that too - embedded at the top of this article - so you won't need to go anywhere else to stay up to date with the latest happenings from Las Vegas all weekend long!
