It was his second consecutive loss to the same opponent, after Poirier secured victory in their UFC 257 fight.
After the fight, McGregor’s long-time rival Khabib took to Twitter and wrote: “Good always defeats evil. Very happy for Dustin Poirier I hope you will get the belt end of the year.”
Last night, McGregor tweeted out what appeared to be a response to Khabib’s initial tweet, and also appeared to be a disgraceful reference to the passing of the Russian’s father.
He wrote: “Covid is good and father is evil?” The tweet has since been deleted from McGregor’s account.
Khabib’s father Abdulmanap passed away due to complications from COVID-19 last July.
He was the long-time trainer of Khabib, and the Russian retired three months later after defeating Justin Gaethje at UFC 254.
He explained: “No way I’m going to come here without my father.
“It was the first time after what happened with my father, when UFC called me about Justin, I talk with my mother three days.
“She doesn’t want me to go and fight without my father but I promised her it was going to be my last fight.
“If I give my word, I have to follow this. It was my last fight here.”
Unsurprisingly, McGregor has received heavy backlash for his tweet.
McGregor embarked on a tirade of tweets last night – which have all now been deleted.
In one tweet, he gave some reasons behind his defeat at UFC 264, and handed out some abuse in the process.
It read: “Jumping the guillotine is not a takedown. Absorbing he kick into the leg is not a check. A doctor stoppage is not a TKO.
“The game goes on bitches. P**s ants to me yous all are. Not even peasants. P**s ants!
“Now get to your stationed vlogger cameras you novice bums.”
