His injury was originally listed as day-to-day, but he was placed on injured reserve on Feb. 10. He has missed six games.Through 49 games this season, Arnott has 12 goals and 12 assists (24 points).Huskins fractured his ankle on Oct. 28 in Calgary and underwent surgery on Nov. 16. He has missed 46 games.In nine games, Huskins has two goals, two assists and a plus-6 rating.With both players ready to return, the Blues are still without Alex Steen (concussion) and Matt D'Agostini (concussion).
