The Blues activated Arnott (shoulder) and Huskins (ankle) off injured reserve Thursday. Huskins missed 46 games after breaking a bone in his left ankle blocking a shot in Calgary on Oct. 28. Arnott was injured on Feb. 3 against the Los Angeles Kings and missed the previous six games. The Blues are without LW Alex Steen (concussion symptoms) and RW Matt D'Agostini (concussion). Steen will miss his 21st straight game tonight and has been out of the lineup since Dec. 27. D'Agostini was injured Feb. 7 in Ottawa and will miss his fifth consecutive game. D Carlo Colaiacovo appeared to have injured his right wrist at practice Wednesday sliding into the corner boards but coach Ken Hitchcock said he's feeling better and hopes to have the left-handed defenseman for practice Friday. F Ryan Reaves is the lone healthy scratch.
