Russian coach Oleg Znarok and Swedish coach Rikard Gronborg got into a heated argument from their respective benches during today's semifinal game at the IIHF World Championships. You can't hear what they're saying, but it's safe to say that the words aren't friendly.

At one point, Znarok points to the locker room(?) and knocks his fists together. (Not sure what that means.) A replay shows Znarok dragging his finger across his throat. (That one's easier to interpret.) He has zero chill.

Russia won, 3-1, but Znarok could face a suspension for his gesture and miss the team's championship game.
