Floyd Mayweather's bodyguard violently shoved opponent Mikuru Asakura during an intense face-off on Tuesday.

Boxing legend Mayweather will do battle with the Japanese MMA fighter in an exhibition bout at RIZIN 38 on September 25.

The two men went nose to nose as they took a closer look at each other at a press conference in Hawaii to promote their upcoming fight before they step foot inside the ring in a few weeks' time.

But Mayweather's bodyguard obviously felt that Asakura got a little bit too close for comfort as he entered his personal space.

He didn't take too kindly to this invasion of his privacy, walking forward and furiously shoving the YouTuber.

Mayweather said nothing but didn't seem to agree with his actions, which he shook his head at.

But after the brief altercation, the two men squared up again for photos before posing for the cameras.

Mayweather, 45, was recently inducted into the International Boxing Hall of Fame in June.

The greatest fighter of his generation struggled to hold back the tears as he accepted the honour for services to the sport.

“I done a lot in my career, but this is by far the best,” Mayweather said, crediting his mum, dad and sister for much of his success.

“I must always give thanks to the man above, always first, ‘cause without God none of this would be possible. My dad is a genius. My dad is a great man, he’s a man with integrity, he’s a stand up guy, and I will always put him first.

“And to the queen, my mother, a great woman, ambitious, she has the will to win in life. So when you take my dad, who’s the best trainer ever, and you take my mother, another queen — you take that king and that queen and you put them together, this is what you get. We all know I look good, I fight good, I’m undefeated, I dominated the sport for 20 years straight.

"But another great thing about my career is the smart investments that I made. This sport was able to put me in a position to be able to make over a billion and then invest my money and double, and triple it. 

“And someone that I never talk about, my oldest sister. Always had my back, always protected me, and always wanted the best for me, and always ran my companies with an iron fist and never got in front of a camera and never got on social media. I want to tell her that I love her, keep up the great work, and I will always have your back. 

“And to one of the best businessmen in the world, my business partner — some call him my business partner, some call him my other dad, some call him my manager, call him whatever you want you want to call him, but we’re gonna call him great, too: Al Haymon. The connection that me and Al have is unbelievable. To be able to work with over 400 fighters and put these fighters in position to be able to take care of their families is remarkable, and that’s what it’s all about."
