The Seattle Seahawks will don their 1990s throwback uniforms in their season opener against the Denver Broncos on Sunday, Sept. 8, at Lumen Field. These popular retro uniforms, which feature a silver helmet, royal blue and apple green jerseys, and silver pants, were worn by the team from 1976 to 2001. The throwbacks made their debut last season in a victory over the Cleveland Browns. This season, the Seahawks plan to wear the uniforms again in Week 6 when they face the San Francisco 49ers. New head coach Mike Macdonald has his players practice in their game jerseys to enhance preparation. The Seahawks' announcement has delighted fans who appreciate the nostalgic significance of the uniforms.
