Legendary boxer Floyd Mayweather beat mixed martial artist Mikuru Asakura via second-round technical knockout in their exhibition boxing match Sunday in Japan.

The 45-year-old Mayweather floored Asakura with a hard right at the end of the second round shortly after taking some punches from the Japanese fighter and YouTuber at a packed Saitama Super Arena.

Mayweather's long-time Filipino rival Manny Pacquiao was ringside for the Rizin Fighting Federation card.

"We were able to give the fans excitement tonight," Mayweather said, calling Asakura a tough competitor. "I want to thank you guys for another unbelievable experience. Thanks for having me. I'll be back."

The 30-year-old Asakura said, "(Mayweather's) reaction speed was unbelievable. His technique is out of this world."

On Dec. 31, 2018, Mayweather knocked out kickboxer Tenshin Nasukawa in the first round of another exhibition match at the same venue in Japan.
