In the week leading up to The Big Chill at the Big House, there will be a lot of activity at Michigan Stadium. Although the Michigan-Michigan State game isn't until Dec. 11, hockey will be played in the Big House on both the Saturday and Sunday the week before.
Previously, a tripleheader involving high school teams was announced. The tripleheader will take place on Dec. 5, starting at 4 p.m. It will feature the following three games: Skyline vs. Father Gabriel Richard, Saline vs. Ann Arbor Pioneer and Ann Arbor Huron vs. Dexter.
The day before, on Dec. 4, there will be a college hockey game between Division III rivals Adrian College and Concordia (the Concordia from Wisconsin, not Ann Arbor). The game will take place at 9:30 a.m. ET, according to Concordia's hockey schedule, so perhaps there will be other games played that day. It's pretty obvious Michigan wants to make use of this ice with many games, so it's certainly possible.
