Is there anything Jim Harbaugh can do to return as coach of the San Francisco 49ers in 2015?

It doesn’t sound like it. Not even a Super Bowl trophy would change the 49ers’ mind, Fox Sports’ Jay Glazer reports. Harbaugh, 50, has been the Niners’ coach since 2011 and has reached the NFC Championship game every year and advanced to the Super Bowl, where he lost to his brother’s Baltimore Ravens team. It’s an impressive record, but Harbaugh’s act is wearing thing with General Manager Trent Baalke, according to multiple reports. The 49ers are 2-2 and play the Kansas City Chiefs on Sunday.

If Harbaugh is indeed cut loose, his unemployment may be brief. His name has been mentioned in connection with the college job at Michigan, where Brady Hoke is in trouble, and across the Bay in Oakland, where the Raiders will have a vacant head-coaching position. Last week, the NFL Network’s Deion Sanders reported that Harbaugh is on thin ice.

“They want him out,” Deion Sanders said on the NFL Network last week. “They’re not on the same page.”

This is significant because Sanders is close to at least one member of the team, Michael Crabtree.

“I really want to know if they’re really playing for the head coach,” Sanders said. “I got a question with that. Are you really down with your head coach, San Francisco 49ers?

We all know people inside locker rooms.”

By early Sunday afternoon, owner Jed York sought to defuse the situation with a tweet:
