Former UFC heavyweight champion Junior Dos Santos has apparently signed a deal with Triller and is going to debut for the company in early 2022, according to a report by TMZ Sports.

TMZ indicates that this debut will likely come on a date in February, against heavyweight contender Kubrat Pulev.

Their bout will be held under the rules of Triller's new Triad Combat fighting system - which matches MMA fighters against boxers under a set of rules intended to “level the playing field.”

Pulev is no stranger to the Triller's Triad Combat system. 

He recently made his debut for Triller - and demolished another former UFC fighter, Frank Mir, in one round. 

Dos Santos (21-9 in MMA) was released by the UFC after suffering four straight defeats. In his last fight with the company, he suffered a TKO loss to at UFC 256 in December of 2020, at the hands of Ciryl Gane

A few months ago, the 37-year-old Dos Santos expressed his desire to enter the sport of boxing - and last month he took a big step in that direction by signing a contract with S-Jam Boxing, which is a management company that guides the careers of boxers such as Joe Joyce, Lerrone Richards, Johnny Fisher, Guido Vianello, and others.

Also on this card, two former champions will collide in another boxer vs. MMA clash.

TMZ reports that former light heavyweight champion Chad Dawson, 39-years-old, will collide with 44-year-old former UFC champion Vitor Belfort, who earlier this year blew away Evander Holyfield in a single round.

Dawson (36-5, 19 KOs), inactive for the last two years, is a lot younger than the 59-year-old Holyfield, who entered the ring after 10 years of inactivity.
