No, seriously.

Joe Riggs is one of the most interesting and entertaining characters in the history of MMA. Making his professional debut in 2001, “Diesel” has some 64 professional contests under his belt, and he’s still just 35 years old.

He’s fought for the UFC, Bellator, Strikeforce and the WEC. He’s withdrawn from a fight due to an injury sustained by shooting himself in the leg.

On Friday, Riggs (47-17) fights in the co-main event of M-1 Challenge 90, which takes place at M-1 Arena in Saint Petersburg, Russia, where he takes on Ukranian middleweight Boris Polejay (18-6).

Is it surprising to hear that Riggs is fighting in some far-flung destination on a show that most people will never see? Absolutely not. Riggs has been on the grind since he was 19 years old, fighting anybody, anywhere, anytime.

What is a little shocking? When curiosity got the better of me, I decided to look up Riggs’ recent record, and guess what – he’s won six straight fights, all of them by TKO.

Seriously.

Riggs was in the UFC as recently as 2016, but a 1-3 run saw him cut from the organization. However, he hasn’t lost since. And the six-fight winning streak stands as the second-longest of his career, falling behind only an eight-fight streak he had in 2004 (as in, all eight of those wins came in the same calendar year).

We see you, Joe Riggs. Do your thing.
