49ers offensive coordinator Greg Roman will interview Saturday for the Minnesota Vikings head-coaching job, one day before San Francisco plays the Carolina Panthers in a divisional playoff game, league sources say.

It will be the continuation of a chaotic week for Roman.

After San Francisco beat Green Bay on Sunday, Roman interviewed in Chicago on Monday for the Penn State head coaching position, a job Vanderbilt coach James Franklin reportedly landed.

Roman then flew back to San Francisco and spent this week preparing for another head coaching interview and Carolina.

It also puts Roman in a tricky spot.

A win would help the 49ers and his credentials but might wind up hurting his candidacy as some teams do not like to wait too long to hire their head coach.

The Vikings also were interviewing 49ers defensive-line coach Jim Tomsula this weekend, sources said.

Information from ESPN senior NFL analyst Chris Mortensen was used in this report.
