1998 Seattle Seahawks season

The 1998 Seattle Seahawks season was the team's 23rd season with the National Football League. A late-season loss to the New York Jets came due to a controversial call when Jets quarterback Vinny Testaverde ran in a touchdown but was downed short of the goalline yet the play was ruled a touchdown; the loss helped knock Seattle out of the playoffs. The 1998 season was the final season for head coach Dennis Erickson.
