Alexander Volkanovski has accepted Conor McGregor's callout and warned the former UFC featherweight champion that 'I'm a whole different beast to what he's used to in this division'.
McGregor went after the Freestyle Fighting Gym standout after he put a beatdown on Brian Ortega in the main event of UFC 266 in Las Vegas.
He promised to remove his head from his shoulders and made a derogatory comment about the Australian's relatively small stature.
In a now-deleted tweet, he wrote: "I’d kick this volovski [sic] head off like it was a rugby ball I was kicking.
"5’4! And full of muscle! Hahahahaha little fart he is.
"Not even a little fart. A shart haahahahaj [sic] jackass."
Volkanovski, 32, responded to McGregor, 33, in his post-fight interview and admitted he didn't understand what the Irishman was trying to say.
“Something about sharting, farting, it didn’t really make sense,” he said to reporters at a press conference in Las Vegas.
But Volkanovski later backtracked on his initial reaction and appeared to welcome the idea of a fight with 'The Notorious'.
“Sounds like he’s off his head,” Volkanovski told ESPN.
“So yeah, good on ya. Enjoy your night!
"But aye, come back to featherweight, I’d love it."
"I reckon he’s a man of the featherweight division, and again, I’ve got the strategy, I’m obviously tough," he added.
"And yeah, I’m a whole different beast to what he’s used to in this division.
"So if he wants to come back down, welcome, I’d love it.
"Hey, if it’s not an option, let’s go for 155. Let’s do it, 155, let’s make it happen.”
McGregor has campaigned mostly at featherweight in his career, winning three titles in two different organisations.
But he did step up to lightweight in November 2016, beating Eddie Alvarez for the UFC lightweight belt at MSG in New York.
Volkanovski and McGregor have long had a healthy rivalry, and have expressed interest in fighting each other.
But it's unlikely the fight will come off unless something crazy happens.
