A Sport.cz article broke the news with their roster release.
Hanzal is a 26-year-old native of České Budějovice. This will be Hanzal's first Olympic games after representing his country in the U18 World Junior Championship in 2005, U20 World Junior Championship in 2006 and 2007 and the World Championship in 2008.
The centerman has 11 goals and 28 points in 38 games this season.
Michalek is a 31-year-old native of Jindřichův Hradec. Michalek represented the Czech Republic in four World Championships and in the 2010 Olympics. The defenseman played five games for the seventh place Czech team in 2010. In total, Michalek has three goals and five points in 36 international games.
The selection of Michalek was somewhat in doubt after he was placed on injured reserve last month with a lower-body injury. He hasn't played since.
In 24 games this season, Michalek has record four assists and 72 blocked shots.
Notable by his absence from the list is Radim Vrbata. The 32-year-old native of Mladá Boleslav has a pair of international gold medals (2001 WJC and 2005 WC) as a Czech and is one of the best goal-scorers in the NHL. He has 11 goals and 29 points in 39 games this season.
