Principality Stadium officials have volunteered to host the Anthony Joshua-Tyson Fury contest should their counterparts at Wembley Stadium fail to comply with the wishes of Turki Alalshikh and Netflix.
The heavyweight bout, between two British superstars, needs to start at prime time in the US to boost audience figures which would mean the opening bell being struck in the middle of the night in the UK.
Wembley officials have not confirmed if a start time of 2am or later will be possible. The London venue’s curfew currently stands at 11pm.
However, should the organizers wish to consider Cardiff as an option then the Welsh Rugby Union (WRU) – owners of the stadium – have stated they can oblige.
“We’d be delighted to host this fight,” a WRU spokesperson told Sky Sports and the BBC.
“We are very keen to attract more boxing to the stadium which has a rich history in the sport, enhanced by its closeable roof, unrivalled sight lines and unique city centre location.”
Should the showdown land in Cardiff, it would mark Joshua’s third outing in the impressive stadium. He defeated Carlos Takam there in 2017 and Joseph Parker the following year.
