Anthony Joshua is set to break a boxing attendance record set by Muhammad Ali 39 years ago when he fights Kubrat Pulev in Cardiff next month.
But fans have been warned of potential travel chaos and major rail service restrictions to Wales – with Millwall also playing away to Cardiff City before the contest on October 28 and the last train back to London at 8.37pm before the main boxing event starts.
Promoter Eddie Hearn is expecting a crowd of nearly 80,000 at the Principality Stadium – which has a roof – once seating configurations have been confirmed.
That would beat the previous record of 63,315 for an indoor fight which was set when Ali fought Leon Spinks in a re-match at the New Orleans Superdome in September, 1978.
Joshua was due to come face-to-face with 36-year-old Bulgarian Pulev at a press conference at the stadium today (Monday 1pm) ahead of the official start of general sale tickets on Tuesday.
Hearn said: “For some time the 02 Arena in London became a kind of spiritual home for Anthony. But since he drew 90,000 to Wembley when he beat Wladimir Klitschko last April, we know he can only fight in stadiums in the UK.
“That is how big and popular he has become.
“It obviously made sense to go to Cardiff in the autumn because there is a roof and it has staged big fights before.
“The Wembley fight sold out more or less instantly and we’re expecting the same for this one.”
“This is a tough fight for AJ because Pulev is very strong and very experienced. But Anthony wants to fulfil all of his mandatory defence obligations whenever they come up because he is determined to unify the world title. He is not interested in abandoning any belts for convenience sake.”
