Matchroom Boxing has announced that former world lightweight champion George Kambosos (pictured) will face a late replacement opponent on Saturday. In his junior welterweight debut, Kambosos is now slated to take on  Queenslandm Australia’s Jake Wyllie (16-1, 15 KOs) at the Qudos Bank Arena this Saturday. Kambosos explained further: "[Original opponent Daud] Yordan just pulled out due to medical issues and now is in hospital. Boxing [is] always the unpredictable. Most importantly, I hope he’s OK as I know he was preparing very hard for this opportunity. Ok so im not just going to chill and wait to smack [IBF champion Richardson Hitchins] in a few months and take his belt. I'm ready to showcase all the work we have be putting in over the last three months and will give a good local Aussie kid a shot!! Five days out, there is no show without me. The undercard needs me and I want them all to shine and be paid for the hard work they have put in. Australian boxing needs me, and victory no matter what, sets up my world title shot next. Jake Wyllie, you are the current Australian 140-pound national champion. You're the only one that hasn’t been disrespectful for a payday, and I like how you have gone about your business, so I’m giving you the Rocky shot!!! But this ain’t a Rocky movie, don’t get it twisted, there is no happy ending. Ferocious statement [coming]. See you all Saturday night. The show goes on, the Ferocious Show."
