Vikings offensive line coach Jeff Davidson was denied permission to interview with the Falcons, according to Fox Sports.

General manager Rick Spielman said during Monday's press conference assistant coaches would need written permission to speak to other teams since they're all still under contract.

Davidson, 46, just finished his third season with the Vikings. He has previously spent time on staff with the Patriots, Browns and Panthers for 14 years before joining former head coach Leslie Frazier's staff.

Davidson was a teammate of Spielman's brother, Chris, while at Ohio State.
