Conor McGregor Tweets and Deletes Ruthless Response to Khabib's Cousin Tapping Out at UFC Moscow

Conor McGregor is as ruthless as a trash-talker and tweeter as he's been as a fighter, especially when it comes to his UFC rival, Khabib Nurmagomedov.

The MMA superstar, who hasn't fought since he suffered defeat at the hands of Khabib a year ago, didn't hold back following cousin Abubakar Nurmagomedov's upset loss in Moscow via submission. Conor tweeted and then deleted a simple message: "Nurmagotaptap."

Talk about showing no mercy.

Abubakar's loss by triangle choke at the hands of David Zawada was surprising to many, but from the looks of it, McGregor wasn't surprised in the least.

Of course, McGregor and Khabib have been feuding for quite some time now. On Friday, Khabib went out and said that his erstwhile foe needed at least 10 wins in a row to earn a rematch against him, far more than the two fights the Irishman initially outlined as he plans his UFC comeback in 2020.

McGregor is doing all that he can to get under his rival's skin-- even if it means taking jabs at the man's cousin.

Game on.
