Former five-time world professional boxing champion, undefeated Floyd Mayweather, faced his next opponent, video blogger Logan Paul, 26, the first time.
Their pre-fight staredown was heated. Paul tried to provoke the 44-year-old American boxer and hit his cap.
The passions ran high, after which Mayweather told his opponent that he will kill him.
Their exhibition bout will take place Friday in Miami, Florida, USA.
The fight was originally scheduled for February 20, but was postponed due to the coronavirus pandemic.
Floyd Mayweather had his previous fight on December 31, 2018 in Tokyo, knocking out kickboxer and mixed martial artist Tenshin Nasukawa (Japan).
