Boxing: Floyd Mayweather Sends Japanese MMA Fighter Mikuru Azakura to the Canvas After Round 2

• Former World champion Floyd Mayweather floored Japan Mixed Martial Arts (MMA) fighter Mikuru Asakura on Sunday in an exhibition bout staged in Saitama, Japan
• Mayweather's bout with Asakura had no judges, meaning the result would not count on the fighter's record
• The American, who was recently inducted into the International Boxing Hall of Fame, retired in 2017 with an unblemished 50-0 record after beating UFC star Conor McGregor in his final fight

Floyd Mayweather knocked out Japanese Mixed Martial Arts fighter Mikuru Azakura with a devastating right hand at the end of the second round in an exhibition fight.

The 45-year-old Mayweather was competing for the second time this year having met Don Moore in Abu Dhabi in May.

Mayweather, who has an unblemished 50-0 career record, kept the bout at arm’s length in the opening round, using his jab to keep the distance.

However, a competitive Azakura landed a stinging body shot on the former World champion in the opening minute.

But a more aggressive Mayweather landed a big overhand right at the tail-end of round two that dropped the Japanese straight to the canvas heavily at the bell.

It was the first time the 30-year-old Asakura, who has a record of 16-3 in MMA matches, competed in a boxing bout, albeit an exhibition.

Following the end of the bout, Mayweather spoke to the crowd afterwards and expressed his appreciation to everyone who came, as well as eight-division world champion Manny Pacquiao.
