The Minnesota Vikings began their second round of interviews for their open head coaching position with Cincinnati Bengals defensive coordinator Mike Zimmer on Tuesday.

Zimmer had interviewed a second time with the Tennessee Titans on Monday before they announced they had hired Ken Whisenhunt as their next head coach.

According to Master Tesfatsion of the Minneapolis Star-Tribune, Zimmer said Tuesday night he has not been offered the job with the Vikings. However, he is expected to remain in Minnesota overnight into Wednesday.

The Vikings have cast a wide net looking for candidates to fill the job vacated by the firing of Leslie Frazier at season’s end. However, many candidates for the job remain tied up with coaching duties this postseason. Denver coordinators Adam Gase and Jack Del Rio, Seattle coordinators Darrell Bevell and Dan Quinn and 49ers offensive coordinator Greg Roman and defensive line coach Jim Tomsula remain as targets for the vacancy. However, the Vikings will have to wait a bit longer on those candidates if they want to hire one of them.

Arizona Cardinals defensive coordinator Todd Bowles and Cleveland Browns defensive coordinator Ray Horton have also interviewed for the position.
