Tyrone Spong faceplant KOs boxing opponent

He hasn't been active lately in MMA circles, but Tyrone Spong is still knocking guys out in spectacular fashion.

"The King of the Ring" ended Lucas Queen's night by KO in a boxing match Friday in Fort Lauderdale. Queen hit the canvas face first after a Spong counter right hand as Queen came in. Brutal stuff. Spong's Blackzilians team posted the video Monday on Twitter. It was his United States boxing debut.

Spong is a former star in GLORY kickboxing and one of the best heavier weight kickboxers in the world. He is also 2-0 in MMA under the World Series of Fighting banner. But the Suriname hasn't fought MMA since 2013 and competed in kickboxing since breaking his leg in a match against Gokhan Saki in 2014.

In the meantime, he has dominated in boxing, accumulating a 4-0 record with four knockouts. Queen's record was a paltry 1-4 coming into facing Spong. But Spong's previous opponent David Gogishvili was a perfect 13-0 before facing the Blackzilians star March 5 in Chechnya.
