As part of the Big Ten's new television deal with ESPN and Fox beginning in 2017, the conference will start playing games on Friday night next season. Not all the members of the Big Ten are excited about the deal, however.
Michigan flat-out told the Big Ten it's not interested in playing on Fridays at all, and on Thursday night, Jim Harbaugh tweeted out that he's "disappointed" in the conference's decision to play on Fridays because it "infringes" on high school football's night.
On Wednesday afternoon, Penn State released a statement saying it isn't interested in hosting games on Friday night, though it will consider playing the occasional Friday night road game.
Michigan and Penn State weren't alone, either. Ohio State is willing to host games on Friday nights, but only under certain conditions, and the same can be said about Wisconsin and Michigan State. Wisconsin released a statement of their own on Wednesday night, essentially stating that it will play on Friday nights, but only before Labor Day, and not every year.
Michigan State already plays one home game on a Friday night during the season, and it doesn't plan on playing any more than that.
