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.
I challenged him to a goalie fight when we chatted before the game, but he didn't want to go. It was strange to see him at the other end of the ice, but I'm sure he felt the same way looking down at our end.
