Floyd Mayweather’s return to the ring this Monday will not be heading to one of the main broadcasters in North America.

Despite Mayweather is one of the biggest Pay-Per-View stars of the modern era, usual network Showtime will not be taking the reigns.

Instead, various streams will be offered for fans around the world to witness the fight live.

Mayweather takes on young, undefeated kickboxer Tenshin Nasukawa in a three-round exhibition contest at Saitama Super Arena.


FITE TV and RIZIN FF are proud to announce RIZIN 14 will be available to stream LIVE on Sunday, December 30th at 10 PM PT / Monday, December 31st at 1:00 AM ET.

Fans in North America (U.S., Canada, Mexico) can order on the FITE RIZIN 14 page and watch via Roku, Amazon Fire TV, Apple TV, Google Chromecast, Mobile (iOS & Android), and via the web at FITE.TV.

This 14 fight card culminates with the main event RIZIN Bantamweight Title fight of Kyoji Horiguchi vs. Darrion Caldwell in a Champion vs. Champion showdown when the current RIZIN Bantamweight champion Horiguchi faces Caldwell who is the current Bellator FC Bantamweight champion.


Mayweather v Tenshin rules:

– Three minutes per round for three rounds

– Straight boxing rules

– Both will wear either RIZIN 8 ounce gloves

– Weight: 147lbs/67.7kg

– No judges

– Confirmed as a full-contact competition, the bout is not going on boxing or MMA records


A 12-time boxing world champion in five weight classes, Mayweather is one of the greatest ever to enter the ring. Buoyed by box office success that saw him shatter nearly all of the revenue records in the sport’s history.

Born in Grand Rapids, Mich., and fighting out of Las Vegas, he is the only fighter to have headlined four events that each generated more than 2 million pay-per-view buys.

Forbes, Fortune, and Sports Illustrated have named Mayweather the world’s highest-paid athlete multiple times throughout a career in which he defeated 24 world champions.


Tenshin Nasukawa was born in 1998 and trained in Karate and kickboxing from an early age by his trainer/father.

He made his professional debut in 2014 at the age of 15 and has since claimed multiple world championships in kickboxing while remaining unbeaten.

Tenshin is now the face for the Rizin Fighting Federation and their biggest headliner to date.

Now aged just 20, Tenshin is a Japanese sensation whose main sponsor is a gaming giant called Cygames.
