The biggest British fight card in a generation just got heavier. Deontay Wilder will face Australia's Jai Opetaia as the co-main event under Tyson Fury vs. Anthony Joshua on December 11 at Cardiff's Principality Stadium, with the card airing live on Netflix.

It's a genuine style clash. Opetaia, the reigning cruiserweight titleholder, is moving up to heavyweight for the bout, per CBS Sports — trading his belt-level dominance at 200 pounds for a shot at the division's most dangerous puncher. Wilder, the former WBC heavyweight champion, returns to a marquee stage looking to reassert himself against one of boxing's most polished technicians.

The undercard addition raises the stakes on a night already carrying nearly a decade of anticipation: Fury and Joshua have circled each other since the mid-2010s, and Yahoo Sports notes the long-awaited showdown finally lands after years of failed negotiations.

For Netflix, it's another tentpole boxing event. For fans, December 11 now offers two heavyweight collisions for the price of one.
