(Follow our live coverage of Usman vs. Covington and Canelo vs. Plant)

U.F.C. 268 is an all-ESPN affair in the United States.

The only place to watch the main card, which begins at 10 p.m. Eastern time, is on ESPN+, ESPN’s streaming service. The pay-per-view will set you back $69.99. If you do not yet subscribe to ESPN+, which normally costs $69.99 annually, you can buy it together with U.F.C. 268 for $89.98, saving $50.

The prelims, starting at 8 p.m. Eastern, will air on ESPN+, ESPNews and ESPN Deportes. The early prelims started at 6 p.m. Eastern on ESPN+.

If that sounds like a lot of ESPN+, well that’s the point. ESPN pays the U.F.C. hundreds of millions of dollars annually for the exclusive right to show the sport in the United States. If you are a U.F.C. fan, or becoming one, you all but have to subscribe to ESPN+.

Canelo Álvarez vs. Caleb Plant

Watching Canelo Álvarez defend all of his belts is a pricey affair. Showtime is selling the pay-per-view for $79.99, and it can be bought through its website, but also many other outlets such as pay television providers like DirecTV, Xfinity and AT&T U-verse, and streaming services like YouTube and Sling. If it is a service you watch television on, it is probably selling the fight.

The main card of four fights begins at 9 p.m. ET, and Álvarez and Plant are expected to enter the ring around midnight Eastern time. The four card preliminary card will not be aired.
