He gassed out after a few minutes on the field, quit his representative rugby league career and on November 6 in Sydney, Nelson Asofa-Solomona will pack it in inside the boxing ring.

That’s what the returning Paul Gallen has promised at least, with the heavyweight crossover king threatening to end Asofa-Solomona’s boxing career after just four fights.

The former Sharks and New South Wales Origin captain will return to the ring after a 16-month retirement when he takes on Asofa-Solomona at the TikTok Entertainment Centre.

Gallen had no intention of making a comeback, but is furious after giving “Big Nasty” tips on how to transition from rugby league to boxing, only to be immediately called out for a fight by the ex-Storm prop.

“For me to have a private conversation with you, personally, and tell you the way I felt, and for you then go and use that against me, I think that’s a shit go,” Gallen told Asofa-Solomona this week.

“And anyone who thinks it’s fair enough is a f***wit to be honest.”

Gallen is giving up 15 years in age and massive height, reach and weight advantages to Asofa-Solomona, but only gives the former Kiwis Test forward a puncher’s chance.

“I don’t think he’s as tough as people think he is,” Gallen said. “I played rugby league against him, and he was a good footy player for 10 or 15 minutes.

“But when I’m constantly on him, constantly pressuring him, how will he handle that?

“He hasn’t faced anyone like that. It’s a fact. Age or not, it doesn’t matter. I’ll be in his face.”

Now 45, Gallen has wins over former heavyweight world champion Lucas Browne and UFC star Mark Hunt, and says Asofa-Solomona will give up on November 6.

“He quit rugby league because the game became too fast for him,” he said. “Rather than try and lose weight and be better, you quit. You quit.

“And that’s exactly what’s going to happen in this fight.

“Once you quit once, it’s in you forever.

“You can’t live with it.

“I know that when you’re pushed and when you have to dig deep, you haven’t got it in you.

“You can’t quit one thing and not quit another. It’s in you.”

Gallen promises to not only make Asofa-Solomona quit in the ring, he says he’ll end his boxing career completely.

“I’m 45 years old and I’m going to beat a 30-year-old weapon,” he said. “A 45-year-old man is going to beat you and you’re going nowhere.

“You’re going nowhere in the sport anyway.

“My question is, what do you do when you lose? Are you going to walk away?

“When you lose, you’re gone.”

Asofa-Solomona made his professional debut in January, tallying wins over Jeremy Latimore, Jarrod Wallace and George Burgess, but admits a loss will all but end his fighting career.

“I have to win every fight,” he said. “It’s in my contract that if I lose, that’s it.

“But in what world does that happen?

“Maybe on Mars or Uranus, but not on Earth.”

Asofa-Solomona calls his decision to step away from the NRL a “mature decision” to try something else.

Gallen will be his toughest test to date after beating an exhausted Burgess in June, but is adamant on knocking Gal out.

“I’m in a game I feel I’m built for now,” he said. “He’s got his own opinion about me and I can’t change that.

“All I can do is turn up on November 6 and do a number on him.

“I’m going to do Australia a favour and knock him out.”
