Dave Allen has told talkSPORT that he was once denied an Anthony Joshua undercard fight just minutes before it was due to happen.British heavyweight superstar Joshua will take on his latest huge stadium show, his biggest yet against bitter rival Tyson Fury on December 11.Allen was so close to fight on Joshua’s Cardiff stadium bill, so has keen eyes on his latest Wales bow with FuryThe blockbuster event will likely see some big names from the UK and US hope to feature, with boxing legend Manny Pacquiao eyed for a role on the bill.It will be a huge platform in front of 80,000 fans at Cardiff’s Principality Stadium, a venue that Allen remembers for all the wrong reasons.Joshua has fought twice at the stadium before, beating Carlos Takam in 2017 and Joseph Parker one year later.British heavyweight fan-favourite Allen has revealed he was due to fight on the card against a late-notice replacement in Scott Saward.He was scheduled in as a ‘float fight’, a clash which is used to fill any available gap on an undercard, depending on the broadcast and scheduling.But unfortunately, as the ‘White Rhino’ has recalled on the latest episode of Fight Night Daily, despite warming up he never made it into the ring.He explained: “I was meant to fight on AJ Takam undercard in Cardiff.“I was meant to box Lenroy Thomas for the Commonwealth title, that fell through and we got a replacement.“I then became a live float where you can go at any time, so I kept warming up and cooling down.“There was no stoppages, but then they came and knocked on the door with Joe Cordina and myself.“He was the Cardiff boy so he had to box, I had to sit it out and never got to see the stadium.“I never left the changing rooms it was unfortunate.”Unfortunately for Allen, he never did throw a punch, but he has gone on to fight on some big shows moving forward.Float fights are currently becoming less common, with fighters often instead used on an early preliminary card before the main broadcast begins.Who is set to be on the Fury vs Joshua bill?Despite Allen’s misfortunes, pretty much every fighter will want to cement their slot on the bill with the bout to be broadcast globally on Netflix.Pacquiao is still in talks to fight on the bill, but will no longer face Shakur Stevenson.Watch Boxing on DAZN*If you click a link in this boxout, we will earn affiliate revenueSign up to DAZN to access the definitive subscription for boxing fans.Upgrade to DAZN Ultimate from just £24.99/month, guaranteeing access to 185+ fights annually, a minimum of 12 pay-per-views at no extra cost, as well as every Lega Serie A match and other elite football access.Alternatively, DAZN Standard is just £15.99/month, with the caveat you will have to pay for pay-per-view events.Click here to sign up.Boxing manager Keith Connolly has suggested some big American names will likely also feature on the bill.A huge all-American clash between unbeaten pair Keyshawn Davis and Richardson Hitchins is reportedly being eyed.Eddie Hearn has suggested he wants Joe Cordina vs Abdullah Mason on the bill.
