You can watch the press conference live here from 7pm.

Rather than defend his featherweight crown, the Dublin fighter has chosen to move up a weight class and take on champion Rafael dos Anjos in an attempt to become the first UFC fighter to hold two weight titles simultaneously.

McGregor has been promoting the press conference, which will also feature women’s bantamweight champion Holly Holm and her challenger Miesha Tate, on Twitter.
