In four weeks' time, at UFC 196, Conor McGregor gets his opportunity to make history.
If he defeats Rafael dos Anjos, he will become the UFC's first fighter to hold belts simultaneously in two weight divisions. Previously, only one fighter - BJ Penn - has had the chance to do so.
It's a bout which doesn't require a major amount of promotion. There's certainly a real chance that it could break UFC records for pay-per-view numbers.
Still, the UFC has released its latest promo for the card, which also features Holly Holm's first defence of her bantamweight belt against Miesha Tate.
The UFC 196 card features three champions - McGregor, dos Anjos and Holm.
However, from the promo, it's clear who the UFC views as its major draw.
