Sean Strickland launched a verbal tirade at Colby Covington for insulting Leon Edwards' late father, leaving Dana White stunned.
Covington has come under fire following his vile taunt aimed at Edwards ahead of their championship clash at UFC 296 in Las Vegas.
The British fighter threw an object at his opponent and had to be strained by security after the American delivered the crass dig.
At UFC's 2024 seasonal presser, UFC middleweight champion Strickland destroyed Covington in an astonishing rant that left White shocked.

"Colby Is an utter piece of s**t," he exclaimed via The Daily Mail. "What it is, if you know Colby on a personal level, he fucked over everybody.
"Him making fun of Leon’s dad is the biggest c**t move you could ever do."
Strickland then referenced Donald Trump, who was denied of walking Covington to the Octagon at UFC 296, adding: "And I take it as a personal insult to me, you guys, the Trump says are Republicans, you guys are my f**king people, the blue collar workers, you guys are my f**king people."
The 32-year-old, who beat Israel Adesanya in his last outing, also applauded Edwards' mother for raising a good man: "Leon's mum, she raised a boy to be a f**king man to win a title to be a good man. And a real fucking American would, would applaud for that. So just so you know, Colby is a fake f**king p****.
"And if he was standing here right next to me, the only f**king thing he would do is call 911 because he is the definition of a f**king b*****."
After weighing in for their UFC 296, 'Rocky' made one final dig at Covington in response to the sick taunt.
"That man is as good as dead," he told Joe Rogan. "Make sure you keep everything you said about my dad tomorrow."
Strickland, meanwhile, will make the first defence of his UFC middleweight title against Dricus Du Plessis at next month's UFC 297 card.
