ST. LOUIS - Blues goalie Jaroslav Halak has been activated from the injured list after missing 12 games because of a groin injury.
Halak was activated before Thursday night's game against the Calgary Flames, and he served as the backup to St. Louis starter Brian Elliott. Halak hasn't played since April 1.
Halak (6-5-1) entered the season as the Blues' No. 1 goalie, but because of groin problems has been limited to only 16 games.
