Conor McGregor booked his ticket to the UFC with a viral knockout in December 2012.
‘Notorious’ flatlined Ivan Buchinger with one punch to become a dual-weight champion with Cage Warriors.
13 years later, Conor McGregor has become the biggest and richest fighter MMA has ever known.
Meanwhile, Ivan Buchinger has amassed a 45-10 record to prove he’s more than just one of the UFC legend’s KO victims.

Conor McGregor’s KO victim gets revenge
Ivan Buchinger got a chance at revenge when he fought at OKTAGON 77 on Saturday night.
The 39-year-old was matched up against a member of Conor McGregor’s SBG team.
Richie Smullen was just getting started in the sport when Buchinger lost to his teammate in 2012.
All these years later, he failed to make it 2-0 for the famous Irish gym against the Slovakian veteran.
Buchinger locked up a ninja choke in the third round of his fight with Smullen to score a come-from-behind win.
Conor McGregor’s next fight
Conor McGregor hasn’t fought since breaking his leg during a trilogy fight with Dustin Poirier at UFC 264 in July 2021.
After four years away from the Octagon, McGregor claims he’s ‘signed’ a deal for his UFC comeback.
The 37-year-old says he will return to action when the UFC holds a show at the White House in June 2026.
“It’s a done deal, signed, delivered,“ McGregor told Sean Hannity earlier this week.
“It ain’t a negotiation. It’s a done deal, signed, delivered.
“McGregor will compete in the White House for America’s 250th birthday.
“Me and Dana are in constant communication, we’ve done incredible business together.
“I’m the highest-generating fighter of all time in the Ultimate Fighting Championship.
“They’ve just signed a breathtaking deal with Paramount, where we go to cable TV. $7.7 billion that deal was approved for.
“I’m ready to rock, baby. Bring in the big dog, the ‘Mac G’.”
