The Kansas City Chiefs have agreed to trade Alex Smith to Washington for a third round pick and Kendall Fuller. Kansas City received interest from at least six other teams.

Smith will sign a four-year extension with Washington averaging $23.5 million per season with $71 million in guaranteed money.

Washington will part ways with Kirk Cousins, who signed a franchise tag each of the past two seasons.

The Chiefs will start Patrick Mahomes at quarterback in 2018.

Smith, 33, came to the Chiefs in a 2013 trade that sent two second-round draft picks to the San Francisco 49ers.
