ANN ARBOR -- Jim Hackett still isn't sure who the Michigan football team will play at night this season.

And right now, Michigan's interim athletic director isn't ruling out anything.

Including a potential night contest between Michigan and Michigan State on Oct. 17 at Michigan Stadium.

"That's the decision we're about to announce," Hackett said Saturday during Michigan's spring game in Ann Arbor. "The rubic around who gets there is not just the athletic director saying 'I love this competitive moment over that,' it's a function of television, it's a function of the social objectives for the universities. It's a function of where the team is with its physical demands of travel at night.

"I think, in our future, who can be in and out of consideration will be an open book. What I'd like to do is to get a strategy for whomever's here, to make sure it's a safe moment. Michigan State presents some unique challenges because of the proximity of the campuses. We could end up with us up there at night or them down here at night with a sea of people being part of the game, and that puts pressure on the safety system. We're trying to work through that."

At this point, Hackett says it's unlikely the team will host a night game for the home opener against Oregon State on Sept. 12, or the season-finale against Ohio State on Nov. 28.

Anything in between those two dates, though, seems like fair game.

"Do you want our incoming students to have their first experience on campus after a few days a football game at night? Maybe not," he said. "Do you want a night game to be in the dead of November at night? Maybe not. There are some physical and social limitations. It's in between that where we've got an opportunity and weather can dictate that."

"We've got the most unique setting in the country for fan experience. We have a city that shows up. Other places can say their stadiums are big (but not like this). Parking, human safety. All of that is part of the consideration where we want to go."

Another thing Hackett shared Saturday was the extremely high rise in season football ticket demand Michigan's seen since hiring Jim Harbaugh as its head coach in late December.

Michigan has a season football ticket waiting list for the first time in roughly seven years, per Hackett. The university has sold out all 81 of its luxury boxes for the 2015 season, something that did not happen a year ago.

As of now, Hackett estimates the program has about 1,500 people on a waiting list who are seeking multiple season ticket seats.

Michigan was famous for its season ticket waiting list during the Bo Schembechler-Lloyd Carr era, but had seen overall ticket demand dwindle under Rich Rodriguez and Brady Hoke.

Michigan brought in a crowd of approximately 60,000 people for its spring game Saturday. Last season, the number sat around 15,000.

Harbaugh's back now, and apparently the fans will be, too.

"We're getting close to figuring out (if all season tickets are sold out for 2015)," Hackett says. "We're getting close to that line. And we'll find out if there aren't any more new renewals and then we can fulfill requests. But we have a demand list for requests right now that we haven't had (in a long time). We have thousands of people who want multiple (season) tickets.

"The season ticket prices, we worked really hard on that. We tried, deliberately, to make an opportunity for every fan that's priced in a certain way to reward loyalty. Loyalty matters. Every (luxury) box we had for sale is gone, there are no openings there. And we had some openings (before Harbaugh was hired). I remember getting informal comments from people after Jim was hired telling me they weren't going to mail a check in until (they saw who the next coach was)."
