WATCH LIVE: Conor McGregor and Chad Mendes take to the scales at the UFC 189 weigh-ins

Let's make some fights official.

The final step before UFC 189 kicks off involves the 22 fighters making weight tonight. The weigh-ins, which are open to the public, will feature the likes of Conor McGregor, Cathal Pendred and Neil Seery all looking to hit their target after their respective weight cuts. Watchful eyes will be on McGregor's opponent Chad Mendes who had less than three weeks notice for his interim featherweight title fight against the Irishman and will presumably have endured a tougher cut than most. The action at what is expected to be the biggest weigh-in event in UFC history gets underway at midnight Irish time. https://youtu.be/V7viQNcua80
