2009–10 Czech Extraliga season

At the end of the regular season, the seventh through tenth-placed teams played in a best-of-five, preliminary playoff round.

In the semifinal round, Pardubice, the highest-remaining seed, were placed against Liberec, and Vitkovice were paired against Slavia.

The bottom four teams from the regular season – Karlovy Vary, Kometa Brno, Mladá Boleslav, Kladno – were placed in a "play-out" relegation group.

[2] The group is structured like a mini-season in which each of the four teams played each of the other four times, twice at home and twice on the road, the same as the regular season format.

Mladá Boleslav won only two of their twelve relegation round games, one in regulation and one in a shootout, and faced the 1. národní hokejová liga winner KLH Chomutov in best-of-seven series.
