Jim Harbaugh focused on this week

Is Jim Harbaugh approaching this weekend's season finale as though it might actually be his final game as coach of the San Francisco 49ers?

"What will happen will happen, what won't happen won't happen," Harbaugh said Monday in what might possibly be his final weekly media conference. "I work at the pleasure of the organization and let them handle the floor.

"We are dedicated to doing our job. Finish what you start and that's the mindset."

A national report over the weekend has Harbaugh being relieved of his duties within 24 to 48 hours of Sunday's game against the Arizona Cardinals at Levi's Stadium in Santa Clara.

It has also been reported that Harbaugh, who has one year remaining on his five-year, $25 million deal with the Niners, has a standing offer of six years and $48 million to return to coach at his alma mater, the University of Michigan.

"As you know, I've not participated in any of the speculation, the unnamed sources, the rumors," Harbaugh said. "I'd ask you to have [the reporter] go back and ask his source for more clarification.

"But I haven't participated; I don't intend to now. I mean, this has been a good 12 months of this kind of thing. So I'm not going to start now."

General manager Trent Baalke, however, confirmed Monday on 95.7 The Game that the University of Michigan has contacted the 49ers about Harbaugh.

"I think the University of Michigan, in reaching out, did handle it correctly," Baalke said. "As I look at it, guys, it's very simple: He's the head football coach of the San Francisco 49ers. ...

"Our focus is on this last game. We'll address next season after this season is over, and not until then. We'll deal with this at the end of the season. That's when we'll deal with it."

After three straight trips to the NFC title game and a Super Bowl appearance, Harbaugh was reportedly almost traded to the Cleveland Browns last offseason. Besides Michigan, he has also been linked to the Oakland Raiders and Chicago Bears.

The 49ers (7-8) are riding a four-game losing streak, the longest of the Harbaugh era. And if they lose to the Cardinals and the St. Louis Rams upset the Seattle Seahawks, the Niners will finish in last place in the NFC West due to tiebreakers.

Asked if he wanted some sort of decision to be made as soon as possible after the final whistle Sunday, Harbaugh did not blink.

"Not into speculation and really never have been," he said.

"The high road's the only road I know. Let's keep on that one."
