Australia's Jake Wyllie has stepped up to replace Daud Yordan against George Kambosos Jnr on Saturday.

The Indonesian veteran Yordan was withdrawn on medical grounds after going to a hospital at home and that has allowed No Limit Boxing’s Wyllie to come in.

The 24-year-old puncher from Queensland will instead top the bill against his compatriot at the Qudos Bank Arena in Sydney.

“This is what dreams are made of,” said Wyllie, who is 16-1-0, 15 KOs. “I’d already arranged tickets to come watch on Saturday and now I’m fighting in the main event."

“I am ready to showcase all the hard work I have been putting in over the last three months, no matter who the opponent is,” said Kambosos,  21-3-0, 10 KOs.

“Boxing is unpredictable and it is very unfortunate to have Daud Yordan medically pull out, five days before the event, but the ‘Ferocious’ show goes on because there is no show without me.

“Victory is the only thing on my mind, no matter what, and it sets up my 140lbs world-title shot next. I want to give a good local Aussie kid a shot. Jake Wyllie, 16-1, 15 KOs, stands out. He is the current Australian 140 national champion; the only one that hasn’t been disrespectful for a payday, and I like how he has gone about his business in the boxing world.

“So, I’m giving Jake the ‘Rocky’ shot. The opportunity, but that’s where it ends. This is not a Rocky movie, don’t get it twisted, there is no happy ending. A ‘Ferocious’ statement is what you’ll see on Saturday night. Victory by any means.”

“First and foremost, we wish Daud Yordan a speedy recovery,” said event promoter Eddie Hearn, of Matchroom. “Now young Jake Wyllie comes in at short notice with a life-changing opportunity to shock the world and wreck George Kambosos Jnr’s plans.

“He is a dangerous puncher with a rising reputation as a stoppage sensation, so expect fireworks this Saturday at the Qudos Bank Arena."
