Former Sydney Rooster and two-time premiership winner Siosiua Taukeiaho is being earmarked as a potential successor to Paul Gallen in the Boxing and Rugby League crossover world.

Buoyed by his new contract with Catalans Dragons, the powerful prop is set to take a fight on the undercard of Gallen's farewell rematch against Justin Hodges on November 23. However, promoters are struggling to find a heavyweight opponent willing to fight him.

CEO and promoter for event promoters No Limit Boxing, George Roseย was puzzled as to why nobody would take the fight.

โ€œWe've had 'Sio' pencilled in to fight on Paul Gallen's undercard, but no one is stepping up to the plate,โ€ Rose told Fox Sports.

โ€œWe've hit up a heap of NRL players who have talked tough โ€” as well as professional boxers, too โ€” but we still can't get him a fight.

โ€œIt's pretty ridiculous really.

โ€œHe hasn't even fought professionally yet. We're giving somebody the best platform you could ask for as a fighter.โ€

Just seven days out from the fight, the urgency to get Taukeiaho's boxing career underway is easy to understand, as his power and speed make for a dangerous combo.

The praise for his ability comes from within the boxing industry itself, with manager Pete Mitrevski - who most notably works with Olympic bronze medallist Harry Garside - a notable fan of the prop's skills in the ring.

โ€œI've been told a few times by guys holding pads that I have power,โ€ Taukeiaho told Fox Sports on his work with Mitrevski.

โ€œBut I just thought trainers say that to all their fighters.

โ€œThe day before flying out for the World Cup, I just did a session with Pete โ€” pads, bag work, stuff like that โ€” and afterwards we had a good chat about me taking this seriously because of my power and speed.

โ€œPreviously, I've never taken boxing seriously. It was more about keeping fit for footy season.

โ€œBut Pete said I could do things in the sport. After hearing that, it made me realise this could be a good opportunity to test myself, chase the dream.โ€

Despite the encouragement, the search for his opponent continues, with Rose laying down the gauntlet for any heavyweight willing to lace up the gloves and become the next Gallen.

โ€œGal is leaving the boxing game after his rematch, so someone has to step up to the plate,โ€ Rose continued.

โ€œIt's a massive opportunity โ€” find the next Paul Gallen on his own undercard - but they have to be quick.

โ€œIf anyone out there thinks they can take down โ€˜TKO' Taukeiaho then hit me up ASAP.โ€
