Khabib Nurmagomedov's manager Ali Abdelaziz sent a warning to Conor McGregor after his win over Donald Cerrone.
McGregor returned to the octagon with a victory in Las Vegas as he defeated Cerrone within 40 seconds at UFC 246.
It was the Irishman's first fight since his infamous defeat to rival Khabib in November 2018.
Khabib is still on McGregor's hitlist as he called out four rivals ahead of his win over Cerrone.
The Russian and his team reacted to the victory with Khabib posting "history will define us" in a cryptic message shortly after McGregor had emphatically beaten Cerrone.
Abdelaziz also posted on social media, writing: "Keep my name out of your mouth boy before you get humbled again."
McGregor and Abdelaziz clashed before the Irishman's defeat to Khabib and the feud looks set to continue.
After the fight, McGregor suggested Abdelaziz could be behind the vile messages that appeared on the timeline of welterweight champion Kamaru Usman.
The posts, which targeted McGregor and girlfriend Dee Devlin, also included details of Usman's bank account.
He said: "I’m skeptical because one came through early, and it had all the hallmarks of that little (expletive) weasel Ali.
"They give him control of the accounts. He had Frankie (Edgar’s) account, he had Henry (Cejudo’s) account. This has been going on a while. He gets it and write something through their thing. "
