OAKLAND, Calif. - Michigan has reportedly reached out to Jim Harbaugh, according to a report from the NFL Network.

The University of Michigan has reached out to #49ers coach Jim Harbaugh, sources say. U-M left convinced he wanted to be an @NFL coach

Harbaugh not wanting to return to college next year comes as no surprise given his competitive nature. When he took the 49ers job in 2011, he mentioned how excited he was to "compete at the highest level." And with his brother John and former college rival Pete Carroll having already won Lombardi Trophies, it's difficult to envision the ultra-competitive Harbaugh willing to leave the NFL for a college job without a championship on his resume.

Rapoport also had this on Harbaugh and Sunday's opponent, the Oakland Raiders.

If Harbaugh has interest in joining the Raiders, then perhaps the 49ers brass could work out a trade of they decide to not bring him back for the final season of his five-year, $25 million deal he signed in 2011.

Harbaugh must sign off on any trade, meaning the 49ers cannot, necessarily, dictate where he lands in 2015. If the team elects to part ways, but still wants compensation for his services, Harbaugh will pick the team, the teams will work out a trade, and he will sign a new contract.

News on Harbaugh's job status has become a Sunday tradition in 2014. Before the team's seasoning-opening win in Dallas, the NFL Network reported Harbaugh was "losing the locker room." Before the 49ers beat the Eagles in Week 4, the NFL Network again broke news noting how unhappy players were to be unable to play music or play cards on the team plane rides.

Monday, Harbaugh said he wasn't concerned about 2015.

“I don’t worry about my future. Haven’t participated in any of that speculation. I think I have a recessive gene for worrying about my own future. What I want is - I want to attack this week. I want to get this right,” Harbaugh said.
