Brady Hoke's Michigan Wolverines defeated Penn State 18-13 on Saturday night to end a three-game losing streak. But it may be too late for Hoke, now that the T-shirts have been printed.

CollegeSpun.com is reporting that "Harbaugh Now" T-shirts made their appearance in Michigan maize and blue outside the Big House before Saturday's game.

Jim Harbaugh criticizes reports of player mutiny but doesn't address the question

Hoke is 29-17 in his fourth season as coach at Michigan, not exactly the numbers Wolverines fans have come to expect from the program. His team is 3-4 and he was roundly criticized for his decision to leave sophomore quarterback Shane Morris in the game after taking a vicious hit to the head in Michigan's loss last week to Minnesota.

Harbaugh, meanwhile, is involved in his own soap opera as coach of the San Francisco 49ers. Despite three consecutive NFC Championship Games and one Super Bowl appearance, Harbaugh appears to be at odds with 49ers management.

ESPN's Adam Schefter wrote that he believes Harbaugh will not be with the 49ers in 2015.

"There's still a lot of season left now, and things always could change," Schefter wrote. "But it feels like there is a lot of strain, a lot of uncertainty and my belief is it would be an upset if Harbaugh is back next season. That's not to say he can't and won't be, but I wouldn't count on it right now. The fact that San Francisco even listened to dealing him last offseason, and Harbaugh preferred not to sign an extension with them before this season, tells me that both sides are open to moving on from one another. But let's see how this season turns out first."

Harbaugh, a former Michigan quarterback, was the school's first choice when it fired Rich Rodriguez after the 2010 season, but the 49ers came calling and Harbaugh couldn't pass up the chance.

The timing appears much better on both sides this time for a Harbaugh-Michigan reunion.
