Comedian and late night talk show host Conan O'Brien was joined by American football players Marshawn Lynch and Rob "Gronk" Gronkowski for a Super Bowl "proxy battle" in upcoming fighting game Mortal Kombat X.

Check out the video above to see O'Brien, Lynch, and Gronkowski duke it out in Mortal Kombat X and react with shock and horror to the games fatalities. Lynch also revealed that he usually likes to play Mario Kart, favouring Toad as a driver.

Mortal Kombat X will be released this April for PS4, Xbox One, PS3, Xbox 360, and PC. Earlier today, developer NetherRealm Studios confirmed that Ermac would be making a return to the cast in the game.

Previously, a report was published which allegedly revealed that publishers pay to have their games appear on O'Brien's Clueless Gamer segment. Past segments have featured Call of Duty: Advanced Warfare, World of Warcraft: Warlords of Draenor, Assassin's Creed Unity, and an axed episode featuring Minecraft.
