Though it's already been reported that the University of Michigan's Board of Regents have approved a resolution that will allow the Detroit Red Wings and Toronto Maple Leafs to play the 2013 Winter Classic at Michigan Stadium, the official word won't be out until Thursday. According to the Detroit Free Press, there are Winter Classic announcements set for 10:30 a.m. at Comerica Park, and 1:15 at Michigan Stadium.
And according to the official Red Wings Twitter account, the major announcements can be found on NHL.com, DetroitRedWings.com and the NHL Network. They're having an announcement for Comerica Park as there will be some events related to the Winter Classic that take place there, including the old-timers games and Great Lakes Invitational.
The Red Wings and the NHL expect to shatter the record for attendance at an NHL game, which is at 104,173 by playing at Michigan Stadium, which has seen more than 114,000 people at a football game. One can expect the NHL to make a big deal about this aspect during announcements.
