Michalek (concussion) isn't expected to play in either of the Blues' games over the weekend, NHL.com's Lou Korac reports. Michalek has yet to provide coach Ken Hitchcock with an indication that he's ready to play, so the Blues will more than likely hold him out of action until the blueliner says he's ready to go. The head injury has kept Michalek out since Feb. 14, predating his arrival in St. Louis prior to the trade deadline.
