The board called the special meeting to discuss renting Michigan Stadium to the league for the outdoor hockey game. The NHL also said it would have a major announcement Thursday at Detroit's Comerica Park — with additional media availability in Ann Arbor that same day.
Buffalo, Chicago, Boston, Pittsburgh and Philadelphia have all hosted the Winter Classic, but a game at Michigan Stadium could draw the league's largest crowd.
The Wolverines and rival Michigan State attracted a Guinness World Record 104,173 people for a hockey game on Dec. 11, 2010.
This year's Winter Classic at Philadelphia's Citizens Bank Park drew 46,967, and the New York Rangers beat the Flyers 3-2.
