Josh Norman & Von Miller Play 'Doom' with Conan O'Brien

Last year, Conan O'Brien had Seahawks running back Marshawn Lynch and Patriots tight end Rob Gronkowski compete against each other in Mortal Kombat before their big Super Bowl game. This year, he invited Von Miller of the Broncos and Josh Norman of the Panthers to play the new DOOM. Norman and Miller weren’t the only NFL players to join O’Brien.
