Boxing promoter Eddie Hearn has stated Cardiff's Principality Stadium is the only suitable UK venue to host a potential heavyweight clash between Tyson Fury and Anthony Joshua in December.
On Monday, Fury - who was in Cardiff on Saturday for the WWE Clash at the Castle event - offered Joshua the chance to fight for a world title, despite the Londoner's recent loss to Ukrainian Oleksandr Usyk.
"I think you've all heard that I'm going to be fighting soon, in the next few months," Fury said in a post on Twitter.
"I think that before I announce an opponent that I need to do this, just in case. Anthony Joshua, I know you've just lost a fight to Usyk and you're beltless at the moment, and I'd like to give you an opportunity to fight me for the WBC heavyweight championship of the world, and the lineal championship in the next few months.
"You're coming off a 12-round fight, so you're match fit, you're ready. I'm giving you a few months of notice. Let me know if you're interested. If not I will select another opponent. Thank you very much, and good night."
Joshua accepted the challenge, responding on Twitter: "Yea calm. I don’t do the online discussions just for clout, so if you're real about it shout @258mgt. I’ll be ready in December. Khalas."
Representatives of both fighters have been holding talks over the details of a potential heavyweight bout between the pair, and Joshua's promoter Hearn has stated that - should the fight take place in December - Cardiff would be the only venue able to play host to the mouth-watering showdown.
When asked by Ally McCoist on Talksport if the fight would be held in the United Kingdom, Hearn responded: "That time of year, you'd only really have one choice which is the Millennium Stadium," he said on Talksport.
"You're leaving a huge amount of money behind to do the fight in the UK, but, guess what, these two also have a huge amount of money."
He went on to add: "We've got our plan in place. We've known what the original plan was. Since he walked out of that ring after getting defeated by Usyk, until a day ago, we've been working on that plan to bring AJ back and move him towards the world heavyweight title.
"If this opportunity presents itself, fantastic. But we've got to keep the move going because I think this is an exciting time for AJ, especially if he gets a shot at Fury. I believe this fight will happen. Will it happen in December? I have my doubts, but we're ready to talk."
Cardiff's Principality Stadium will host four rugby autumn internationals in November, meaning the fight would likely have to be scheduled for the middle of December for it to be held in the Welsh capital.
Wayne Pivac's side face New Zealand on November 5 before hosting Argentina seven days later. They then face Georgia in Cardiff on November 19 before rounding off their 2022 schedule against Australia on November 26.
Joshua's loss to Usyk in August was the third of his professional career while Fury remains undefeated having won 32 of his 33 bouts, drawing one against Deontay Wilder.
Watford-born Joshua has twice fought at the Principality Stadium, beating Carlos Takam at the 74,500-seater venue in 2017 before overcoming Joseph Parker on the same stage in 2018.
