On Virgin Media
Virgin customers can watch through Sky Sports Box Office. It will cost £19.95 for standard definition or £20.95 for HD.
You can watch through the UFC app on the Xbox One. However, it seems this feature may only be available in the US. We've checked here in the UK, and i says Content Blocked. Sky Sports Box Office should have exclusive rights to show the fight at home in the UK.
If you don't have a way to watch the fight at home, you can take a trip down to your local Vue cinema to watch it on the big screen. Tickets at Vue cinemas in London will cost £22.99, or screens outside the capital will charge £20.00. Screenings begin at 11.45pm on Saturday night, and last until just gone 7am on Sunday.
BBC Radio 5 Live
If you're happy not to watch, you can listen to the commentary free on BBC Radio 5 Live. The boxing coverage will start at 5am BST, but the commentary will be repeated every hour from 6am, so you can catch up with the action on Sunday morning.
If you're watching at home in America, you can order the fight through Showtime PPV for a rather costly $99.99 for high definition, or $89.99 in standard definition.
Live in Las Vegas
However, if you have very deep pockets, you can still get tickets to see the fight live in Las Vegas. Tickets range from $1,500 all the way up to $15,000. That £20 fee to watch it through Sky suddenly seems incredibly reasonable.
