Kovacevic directed his elbow to the head and neck area of Slovakia's Tomas Kopecky during a collision in front of the net in Saturday's game, the International Ice Hockey Federation said in a statement.
Kopecky left the ice after the hit and did not return for the rest of the game.
Slovenia, who went on to win the game in the greatest moment of their ice hockey history, will play the United States later on Sunday.
