Kirk Cousins will reportedly file a grievance with the players' union against the Washington Redskins if they designate him as their franchise-tag player, according to the Washington Post's Kimberley A. Martin.
Teams will be able to designate franchise and transition tags beginning on Tuesday and will have until March 6 to make those decisions.
If the Redskins sign Cousins to the franchise tag for the third year in a row, he will be unable to become an unrestricted free agent when the new league year begins March 14.
