Donald Cerrone said he will "f**k up" Conor McGregor if he trash talks about his family in the build-up to their UFC 246 battle.
The 36-year-old from Denver isn't normally one for trash talk and insists it would take a serious low blow to irritate him.
McGregor is known for his brash, bold trash talking and often gets under the skin of his opponents.
But Cerrone told MMA Fighting: "The thing is you'd really have to go low, talk about my grandma or my kid and then it would put it on another level.

"You understand what I'm saying? Then I'll just come f**k you up in the lobby type s**t."
Speaking about McGregor's trash talking, Cerrone admitted: "He's the best at it."
He added: "I don't think it's ever going to go that way. He understands that. We're fighting, he can talk about that all he wants but don't low blow."
McGregor and Cerrone will square off on January 18 in Las Vegas in what is an eagerly awaited return to the octagon for the Irishman.
The pair had a run in at a press conference in 2015 ahead of McGregor's UFC 194 clash with Jose Aldo.

Cerrone was also part of the media event with an upcoming bout against Rafael dos Anjos when the pair traded verbal blows.
But Cerrone said: "That's just media boys digging and shoveling for s**t to bring up.
"That's all that was. Conor hasn't said anything bad about me so you've got to go get old sh*t out."
