Nelson Asofa-Solomona has settled his bitter feud with Paul Gallen with a savage first-round knockout in the pair's heavyweight stoush in Sydney.
In sickening scenes at TikTok Entertainment Centre, Gallen laid prone on the canvas for several minutes after the Big Nasty landed a half a dozen brutal blows to the 45-year-old's head.
The former Melbourne Storm enforcer then jumped into the crowd and appeared to lash out at a fan as Gallen received medical treatment.
"I should not behave like that. I'm sorry," Asofa-Solomona said.
The two premiership-winning NRL greats had engaged in a spiteful war of words that Asofa-Solomona threatened to turn physical during Wednesday's official pre-fight press conference.
But he left his biggest statement for the ring.
In addition to beating Sonny Bill Williams in a split decision in the pair's overdue grudge match last year, Gallen had taken care of fellow retired NRL stars Justin Hodges, Ben Hannant, Darcy Lussick, John Hopoate and Junior Paulo during his 20-fight pro career.
But Asofa-Solomona refused to join the long lost and instead added Gallen to his own unbeaten record from four bouts, all coming via knockout.
The Big Nasty had laid out George Burgess, Jarrod Wallace and Jeremy Latimore but nothing nowhere nearly as vicious as Friday night's destruction.
A host of Kangaroos including Sam Walker, Latrell Mitchell, Cameron Munster and Pat Carrigan enjoyed ringside seats as the two-metre-tall man monster delivered on his promise to "do a job" on the former NSW State of Origin captain and Cronulla premiership-winning captain.
In the most-anticipated bout of the undercard, Ahmad Reda added the more experienced and heavier Jake Wyllie (19-3) to his perfect record of 10 wins with a split decision points victory.
Wyllie caused a weigh-in fiasco when he stood on the scales two kilograms heavier than the 61kg lightweight limit on Thursday, but it didn't faze Reda.
"I wasn't afraid to jump in with him," the victor told his home fans.
"I believe in myself all the way and I believe I'll smash anyone in Australia. And once I clean out my backyard, I'm going overseas."
