Halak will get his first start since March 21 at Anaheim, as Elliott has started the last three games -- all shutouts -- but will sit out tonight.
The Blues activated winger Matt D'Agostini, who missed the last 25 games with a concussion, but he will not play tonight. Also, Andy McDonald (shoulder) will not play, but coach Ken Hitchcock said after Thursday's morning skate McDonald would play Saturday vs. Columbus. Also scratched are right wing Chris Porter, left wing B.J. Crombeen and defenseman Ian Cole.
Defenseman Roman Polak (bruised knee) did not accompany the team to Chicago, but could return to the lineup Saturday as well.
