JIM HARBAUGH has kept quiet about the speculation surrounding his future for nearly a year.

So he has no plans to participate now as he begins what could be his final week coaching the San Francisco 49ers.

He wouldn't say whether 49ers executives had come to him to let him know whether his alma mater, the University of Michigan, reached out about bringing the coach to Ann Arbor.

After Sunday's 38-25 overtime loss to San Diego, Fox Sports reported that the 49ers and Harbaugh would cut ties within 24 to 48 hours after the season ends.

"Well, as you know, I have not participated in the speculation, the unnamed sources or rumors, or asked you to have Jay Glazer go back and ask his source for more clarification," Harbaugh said yesterday. "I haven't participated and I don't intend to.

"What will happen will happen, what won't happen won't happen."

Harbaugh, who turned 51 today, has lost four straight games for the first time in his 4-year stint. He has 1 year remaining on the $25 million, 5-year contract he signed in January 2011 to leave Stanford for the 49ers (7-8). San Francisco finishes its disappointing first season at $1.3 billion Levi's Stadium on Sunday hosting Arizona.


* Detroit center Dominic Raiola has been suspended for one game after he stepped on Chicago defensive tackle Ego Ferguson on Sunday. The punishment was handed down by Merton Hanks, the NFL's vice president of football operations. The league said this was Raiola's sixth rules violation related to player safety since 2010.

The Lions (11-4) clinched a postseason berth Saturday when Washington beat the Eagles. Raiola can appeal the suspension.

* Cleveland rookie quarterback Johnny Manziel will sit out the season finale at Baltimore with a hamstring injury he suffered during Sunday's loss to Carolina in his second career start. Manziel's injury, coupled with a shoulder injury to Brian Hoyer, could force the Browns to start undrafted rookie quarterback Connor Shaw.

* Arizona coach Bruce Arians said he's leaning toward starting rookie quarterback Logan Thomas in the regular-season finale.

Arians insisted the decision is not a reflection on how Ryan Lindley played in Sunday's 35-6 home loss to the Seahawks.

Arizona (11-4) still can clinch the NFC West and No. 1 seed in the playoffs if it beats San Francisco and the Seahawks lose at home to St. Louis.

* St. Louis coach Jeff Fisher said he doesn't expect any of his players to be fined for their participation in a brawl in the first half of a loss to the Giants on Sunday. Fisher said accusations of dirty play by New York defensive end Jason Pierre-Paul and others are overblown.

On the play that led to the brawl, Rams linebacker Alec Ogletree carried his tackle of wide receiver Odell Beckham Jr. well out of bounds and then rubbed it in. Ogletree was jumped from behind by wide receiver Preston Parker and in the ensuing fracas Rams defensive end William Hayes had his helmet ripped off.

* Chicago quarterback Jimmy Clausen will miss the final game of the season because of a concussion, and Jay Cutler will move back into the lineup and start against Minnesota.
