Anthony Joshua is preparing for a pivotal rematch against Andy Ruiz Jr just six months after a shock defeat against the Mexican-American in New York.
Ruiz felled Joshua four times in a stunning seven-round victory, and Joshua is now fighting to stay in the conversation at the top of the heavyweight division.
Deontay Wilder and Tyson Fury are due to fight at the start of 2020 and another defeat could leave Joshua with a long wait to face either, having once seemed destined for unification bout.
Joshua-Ruiz 2 takes place in Diriyah, Saudi Arabia on December 7.
Here is how you can ensure you do not miss a moment of the action on another big night for British boxing.
The fight is being shown on Sky Box Office in the UK, which is on channel 491 for standard definition and channel 492 for high definition.
