The Vikings announced their hiring of Bengals DC Mike Zimmer as their new head coach on Wednesday.
With Zimmer's departure, it's said that Cincy will promote LB coach Paul Guenther to take over their defense.
That leaves Cleveland as the last remaining vacancy.
If the Browns are insistent upon holding out for Adam Gase, and he sticks to not interviewing until the Broncos' season is over, then their wait could be as long as another 2.5 weeks, if Denver can defeat New England on Sunday.
Until then, Cleveland will keep itself busy by interviewing Bills DC Mike Pettine.
Ken Whisenhunt may try to bring Chargers TE coach Jason Michael along with him as his OC in Tennessee.
With Jim Caldwell having taken the head job in Detroit, Baltimore interviewed Mini Shanny about coordinating their offense.
Peyton Manning apparently made an unsolicited call to Lions GM Martin Mayhew to support the case for hiring Caldwell.
