How to watch Anthony Joshua vs Andy Ruiz Jr rematch: live stream options and TV channel information for the UK
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.

What have the fighters been saying?
Ruiz on facing a slimmed down Joshua:
"I saw videos where he looked slimmer. I don't know if that's an advantage or a disadvantage.
"I don't know if he will take the punches as well as he did when he weighed more."
"Me? People are saying I lost too much weight, I won't be strong, he will move me around. I am losing eight pounds from what I weighed on June 1. I'll still be the same, I'll still be strong."
Joshua on that knockout punch:
"Why did I say it was a punch from the gods? Because I train in a certain way that means he shouldn't hit me with that shot. So I said it was sent from the gods.
"But for him, for Andy? That's the shot he landed because he trained for it.
"I don't worry too much what he's doing. He knows what he's doing. I have to focus on myself."
