The 2011 IIHF World Championship rosters consisted of 397 players from 16 national ice hockey teams. Organised by the International Ice Hockey Federation (IIHF), the 2011 IIHF World Championship, held in Bratislava and Košice, Slovakia, was the 75th edition of the tournament. Finland won the tournament for the second time defeating Sweden 6–1 in the final.[1][2]
Before the start of the tournament, each participating nation had to submit a list of players for its roster. A minimum of 15 skaters and two goaltenders and a maximum of 20 skaters and three goaltenders had to be selected. After the start of the tournament, each team was allowed to add additional players to their roster, for a maximum of 25. Once players were registered to the team, they could not be removed from the roster.[3]
To have qualified for the national team under IIHF rules, a player must have met several criteria. He must be a citizen of the nation, and be under the jurisdiction of that national association. Players are allowed to change which national team they represent, providing they fulfill the IIHF criteria. If participating for the first time in an IIHF event, the player was required to have played two consecutive years in the national competition of the new country without playing in another country. If the player has already played for a national team before, he may switch countries if he is a citizen of the new country, and has played for four consecutive years in the national competition of the new country. This switch may happen only once in the player's life.[4]
