ANN ARBOR (AP) — Jim Harbaugh will stay at Michigan after all, ending his dalliance with a return to the NFL after interviewing with the Minnesota Vikings for their head coach vacancy Wednesday.

The Vikings have targeted Los Angeles Rams offensive coordinator Kevin O’Connell for the job instead, though they can’t formally make that move until after Rams play in the Super Bowl.

In the meantime, Harbaugh will be back at his alma mater for an eighth season.

“With an enthusiasm unknown to mankind!” Harbaugh said in a text message to The Associated Press.

According to a person with knowledge of the decision, no offer of the job was made to Harbaugh. The person spoke to the AP on condition of anonymity because details of the process were not being made public by the university or the team.

The Vikings fired Mike Zimmer after a second straight losing season. He made the playoffs three times in eight years. General manager Rick Spielman was fired, too, and replaced last week by Kwesi Adofo-Mensah, the former vice president of football operations of the Cleveland Browns.

Adofo-Mensah started his NFL career in research and development with the San Francisco 49ers, where he overlapped one year with O’Connell.

Harbaugh is 61-24 at Michigan, which went 46-42 in the seven seasons before he arrived. He guided the Wolverines to the College Football Playoff for the first time this season, winning the Big Ten for the first time since 2004 and snapping an eight-game losing streak to rival Ohio State.
