STATE COLLEGE, Pa. (AP) — No. 2 Michigan will be without coach Jim Harbaugh on Saturday against No. 9 Penn State, after a judge did not issue a ruling on the school’s attempt to at least temporarily lift the Big Ten’s penalty against the Wolverines for a sign-stealing scheme.

Michigan athletic director Warde Manuel said 90 minutes before kickoff that Harbaugh would not be at Beaver Stadium with the team and a hearing in the school’s lawsuit challenging the Big Ten’s punishment of Harbaugh was scheduled for Nov. 17.

“We look forward to presenting our case next week where we intend to demonstrate that the Big Ten has not acted legally or fairly,” Michigan said in a statement.

On Friday, hours after the Big Ten banned Harbaugh from coaching the rest of the Wolverines’ final regular-season games as punishment for an in-person-scouting and sign-stealing operation, the coach and his alma mater filed a request for a temporary restraining order against the Big Ten and Commissioner Tony Petitti.

Their attorneys asked for a speedy decision from a judge in Washtenaw County, Michigan, that would allow Harbaugh to coach against the Nittany Lions in the top-10 matchup.

“The harm to the university’s student-athletes would be irreversible,” attorneys for Michigan and Harbaugh said in the filing.

But it was to no avail.

Offensive coordinator Sherrone Moore will serve as acting head coach.

Michigan already has played three games this season without Harbaugh on the sideline. He served a school-imposed suspension for the team’s first three games as penalty for an unrelated NCAA recruiting violations case.

Michigan let a different assistant assume the role of head coach each week, with Moore getting one game, defensive coordinator Jesse Minter getting another and special teams coordinator Jay Harbaugh and running backs coach Mike Hart splitting a game.

The Wolverines easily won all three against East Carolina, Bowling Green and UNLV.

Harbaugh returned in time for the conference schedule.

About 2 hours and 45 minutes before kickoff Saturday, four buses carrying Michigan players, coaches, Manuel and other staff were greeted by a few dozen Michigan fans lined up behind steel barriers.

Some cheered and yelled “Go Blue!” as the buses emptied. There was no sign of Harbaugh.

One fan yelled out to Manuel: “Let’s join the SEC!”

Manuel raised a hand to acknowledge the fans, but otherwise Michigan entered the stadium with little fanfare.

The Wolverines went through the normal warmup routine before the game, with some players coming out to the field for some light stretching in sweatsuits.

All-American running back Blake Corum wore a ski cap with the slogan “Michigan vs. Everybody” on it.

The conference disciplined the school Friday for an elaborate, in-person scouting scheme that is also being investigated by the NCAA. Michigan leadership insists conference bylaws require the NCAA investigation to play out and that Petitti overstepped his power by doling out punishment.

The Big Ten noted that Michigan is only arguing procedure and process and had conceded the impermissible conduct went on. Conference rivals have been angry and frustrated as evidence mounted that a former low-level staffer was buying tickets to the games of Michigan’s opponents and sending people to record video of sideline signals.

The rare punishment of a national championship contender in the final stretch of its season and one of college football’s most successful coaches by its own conference has become one of the biggest stories in sports.

On the field, Michigan has been the most dominant team in the country, beating its opponents by average of 36 points per game and not allowing more than one touchdown in any game. The Wolverines’ competition so far has been the only argument against its excellence. Penn State will be the first ranked team Michigan has faced.

Harbaugh’s team is vying for a third straight Big Ten championship and appearance in the College Football Playoff.

After Penn State, the Wolverines play at Maryland before the traditional regular-season finale against heated rival Ohio State. The third-ranked Buckeyes visit Ann Arbor, Michigan, on Nov. 25.

The Big Ten’s penalty would allow Harbaugh to return for the Big Ten championship game and the playoff, if Michigan makes it.
