MMA bad boy Conor McGregor had strong words for Floyd Mayweather and Tenshin Nasukawa after their match was announced earlier this week by RIZIN for the Dec. 31 event in Saitama.

“The Notorious”, who was stopped in the 10th round by Mayweather in a boxing match, called the 50-0 boxer “mad little bastard” and asked if Nasukawa was “Jackie f*cking Chan” in a profane Instagram post.

It didn’t take long for the Japanese star to respond to McGregor’s post.

Hello, Mr. McGregor.

My Name is Tenshin Nasukawa.

I am not Jackie Chan.

I promise to avenge your loss, so please watch my fight.@TheNotoriousMMA pic.twitter.com/gSN53svsqs — 那須川 天心 (@TeppenTenshin) November 6, 2018

Nasukawa last fought in September, defeating UFC veteran Kyoji Horiguchi in a kickboxing match in Japan.

He takes on Mayweather next at RIZIN 14, which is scheduled for the Saitama Super Arena in Saitama, Japan.

Conor will just have to wait his turn.
