Halak, 27, has appeared in five games this season posting a 3-0-0 record including a 2.10 goals-against average and an .889 save percentage, and is tied for the NHL lead with two shutouts. He had been out with a groin injury.
The Blues are 0-3-1 since starting the season with six wins in their first seven games.
The team also assigned goaltender Jake Allen to their American Hockey League (AHL) affiliate, Peoria Rivermen.
It's pretty crazy, but believe me when I say we didn't draft these players with the mindset we had to because they had good hockey-playing dads. It just turned out that way. But we're certainly glad they're a part of our organization.
