Michalek, the NHL's leading goal scorer with 19, was injured when he collided with teammate Erik Karlsson in open ice during the third period of Tuesday's game.
The news continues a harrowing recent trend of promising young NHL stars going out with concussion issues. Penguins center Sidney Crosby is out again with concussion-like symptoms after playing only eight games following a 10-month absence as a result of a concussion suffered in the 2011 Winter Classic.
Also, Flyers center Claude Giroux, the league's points leader, is out indefinitely after suffering a concussion in Saturday's 5-2 win over the Tampa Bay Lightning, and, Hurricanes forward Jeff Skinner, the 2011 Calder Trophy winner, is also out with a concussion.
