Holds on coordinator interviewing

The Minnesota Vikings have interest in both Cincinnati Bengals coordinators: OC Jay Gruden and DC Mike Zimmer, per NFL.com's Ian Rapoport. Other teams with vacancies have expressed interest in San Diego Chargers OC Ken Whisenhunt. The Chargers and Bengals are squaring off this Sunday in an AFC Wild Card playoff game, and thus teams are kept waiting a bit longer to interview these candidates.
