What happened: Denver's throwback restores the classic D logo to its Legacy Blue helmet. Seattle's retro set pairs a silver helmet with royal blue and apple green.
Why it matters: The uniform pairing revives the look of two former AFC West rivals. The national broadcast gives both throwback sets a prime-time regular-season stage.
By the numbers: Seattle used its original uniform family from 1976 through 2001. Denver introduced the D logo in 1968 and returned it to the helmet in 2024 for the first time since 1996.
What to watch: Watch for additional throwback dates when each club finalizes its 2026 uniform schedule.
