A regulation-time victory would have been enough for the Slovakian team to progress instead of the US.

A first-period wrist shot from Christian Jaros put the European side in front, but US forward Brock Nelson made it 1-1 off a pass from David Warsofsky.

Nick Foligno put the Americans 2-1 up early in the third period before Pavol Skalicky turned Tomas Marcinko's shot into the net to draw scores level again.

Slovakian goaltender Julius Hudacek was pulled in an attempt to win the game in regulation-time, but by the time Marko Dano scored the overtime winner it was too little, too late.

The US, who have also lost to Germany this week, have not won the world title since 1960 but have made the last-eight every time since 2010.

They will now be looking to match or improve upon their bronze medals won in 2013 and 2015, but will have their work cut out against Group A table-toppers Czech Republic.

The Czechs were made to work hard for their fifth win of the tournament before beating Switzerland 5-4 at Moscow's VTB Ice Palace.

Russia beat Sweden 2-0 to claim second place in Group A, with the Swedes third.

Denmark secured the fourth spot despite not playing today, with Norway missing out despite beating Latvia 3-1.

Belarus beat France 3-0 today in Group B.

Goals from Tommi Kivisto, Leo Komarov, Mika Pyorala and Jarno Koskiranta then proved enough for Finland to shock Canada and to top the group.
