Andy Ruiz Jr pulled off one of the biggest upsets in recent boxing history when he knocked out world champion Anthony Joshua in Madison Square Garden, and the rematch between the pair is already hotly anticipated.
Having entered the first fight as a massive underdog, Ruiz won't be underestimated this time around. Still, Joshua will no doubt enter as favourite.
While no date has been set as of yet, speculation continues to mount around the venue for the fight.
Many had it assumed that it would once again take place in America, with Joshua keen to avenge his debut loss on US soil. That is by no means a certainty.
Ruiz tweeted earlier this week that he wants the rematch to take place in Mexico, while Joshua would like to bring it back to the UK. However, he acknowledged to Sky Sports that Ruiz's status as champions made this difficult:
We're doing a lot of talking about what he wants but he doesn't call the shots I don't mind fighting in America because I've done it before.
I went there off my own back so for the rematch I would love it to be in Cardiff but it's going to be on neutral ground; Ruiz is the champ so he will make some calls.
Somewhere not previously mentioned, but now considered a real possibility, is Saudi Arabia.
Mike Coppinger of The Athletic has reported that the Middle Eastern country is seen as a real option to host the bout. Saudi officials are keen to bring more major sporting events to the country, and negotiations have been positive.
Coppinger believes Joshua is open to fighting in the Middle East, with Qatar and Dubai also a possibility.
Ultimately, despite Ruiz being world champion, it will be Joshua and Eddie Hearn that will have the final say on the fight's location as per the rematch clause placed in the contract for the first fight.
