World heavyweight title contender Alex Leapai has vowed to "bash" Wladimir Klitschko and emerge as Australia's next boxing champion on April 26.
It was enough to make any NRL rival shudder in fear.
World heavyweight boxing title contender Alex Leapai pledged his allegiance to the Broncos before donning a Brisbane jersey on Tuesday.
Thankfully for the Broncos' foes, former Cowboys scholarship player Leapai was just attending his final hometown promotion ahead of his title fight with Wladimir Klitschko in Oberhausen, Germany on April 26.
But it seems Klitschko won't get off so lightly.
Leapai has been given a token "puncher's chance" against the WBO, WBA, IBF and IBO title holder who has not lost in 10 years.
However, the Queensland battler (30-4-3 record, 24 KOs) said he had more than one lucky shot lined up for the towering 38-year-old Ukrainian (61-3, 51 KOs).
"In boxing one punch can change the whole story but I am not depending on that one punch," said Leapai who leaves for Germany on Monday night.
"I will be honest. I am going out there to bash him, not just one punch."
Broncos players appeared in awe of powerhouse Leapai when he lobbed at training on Tuesday.
And there was a very real chance they could have lined up against him in the NRL if fate had not stepped in.
Leapai revealed he received a North Queensland scholarship in 1997 but his NRL dream was cut short when he embraced his penchant for boxing - regrettably on the footy field.
"I did play football but I did a few stupid things and I got banned from footy," Leapai said.
"I was supposed to play Colts (under 20s) for the Cowboys but it didn't happen."
Not that Leapai is regretting his life choices these days.
The underdog will bank $1.5 million for the fight win, lose or draw - not that he is considering anything but success against the giant Ukrainian.
"I am training for 12 rounds and this is Germany we are going to, it's really hard to win there especially against this guy," he said.
"But to be honest this is not going to go the distance.
"I am going to knock this guy out.
"On April 27 Australia is going to have a new heavyweight champion."
