Zimmer originally interviewed with the Titans on Thursday, a day after his initial chat with the Minnesota Vikings.

It was believed that with the Seattle Seahawks advancing to the AFC Championship game, the Titans would accelerate their decision to fill the head coaching vacancy.

Seahawks defensive coordinator Dan Quinn was a favorite in Tennessee. After having not interviewed him this week, the Titans, per league rules, were prevented from an initial interview until after the Super Bowl, putting Zimmer back in play with Tennessee.

Zimmer is scheduled for a second interview in Minnesota on Tuesday. According to Ian Rapoport with the NFL Network, no other candidates are scheduled for a second, making it likely that it's Zimmer's job to lose.
