Michalek (concussion) is starting to close in on a return to the lineup, NHL.com's Lou Korac reports. Michalek has yet to make his debut with the Blues due to the concussion that predated his acquisition, but he's made positive progress in his recovery over the last several days. He resumed skating late last week and was on the ice again for Wednesday's optional practice. It seems a bit unlikely that he'll be cleared to play in time for Thursday's game against the Flyers, but he may have a realistic shot at playing Saturday versus the Wild.
