Conor McGregor praised Tyson Fury and Deontay Wilder for their heavyweight epic - then took a swipe at Dustin Poirier.
Fury and Wilder served up a classic trilogy fight in Las Vegas with the Brit prevailing in the penultimate round.
He had to twice pick himself up off the canvas to do so before delivering a brutal final stoppage with four minutes of the fight remaining.
And while McGregor was quick to congratulate the bitter rivals, he also drew comparisons with his own trilogy with Poirier.
The pair clashed for a third time this past summer with Poirier winning when McGregor broke his leg at the end of the first round.
And amid his reaction to Fury's win, he criticised Poirier for celebrating a "freak injury".
"Great fight that, both warriors, both winners," McGregor wrote on Twitter. "Hard to not be impressed with Deontay there; against the much larger man and almost got it done.
"Great fight [but] 40lb in weight difference is A LOT. Fair play both men there, very enjoyable fights they have had together. Respect.
"Their skill levels are unique but very close. A great heavyweight trilogy that was. I love when it gets set for certain and both have an honourable showing.
"Not the fam in the ring fake celebrating after a freak injury etc etc you know the gig, God bless the real in this world.
"Congrats Tyson and Paris. Me and Dee are so happy for you and the kids. Congrats Deontay and Telli also. Was great meeting you guys recently.
"A real proud showing that was, and could have went either way. Amazing! Happy Sunday now today with the cheddar and the memory’s God bless."
McGregor's reaction after his defeat by Poirier was much-criticised after he targeted his opponent's wife Jolie.
"Your wife is in my DMs, hey baby," he jeered as Poirier was leaving the octagon.
"Hit me back up I'll chat to you later on, I'll be at the after party at the Wynn night club. You look in bits you little h**!
"This is not over! If I have to take this outside with him it's on outside I don't give a b*******."
McGregor underwent surgery immediately on his broken leg and has remained in the United States since.
He is not expected to return to the cage until next summer but has insisted he has no plans to retire.
Poirier, meanwhile, is expected to challenge lightweight champion Charles Oliveira in December.
