A pair of Slovakia players have received suspensions after incidents during a 6-1 loss to Team USA on Tuesday.
Martin Marincin received three additional games for a hit to the head of American forward Jason Zucker, while defenceman Peter Hrasko was assessed two additional games for a hit to the head on forward Jerry D'Amigo.
Both players received a match penalty and an automatic one-game ban at the time of the incidents. The supplementary suspensions are in addition to the original single-game bans.
Canada's Zack Kassian also received an extra one-game suspension for a hit to the head of Czech Republic defenceman Petr Senkerik.
Sweden has lost star forward Gabriel Landeskog to a high ankle sprain, and the 18-year old is a longshot to play again in this year's World Junior Championship.
Landeskog, who is captain of the OHL's Kitchener Rangers, hurt his ankle in his last OHL game against the Guelph Storm and the injury got progressively worse while he has been with Team Sweden. He is officially listed as day-to-day by Team Sweden.
Landeskog is having a superb year for Kitchener with 25 goals and 20 assists in 32 games. He is projected by many to be a top-five pick in next year's NHL Draft.
