What happened: The clubs will become the first opponents to use their Rivalries sets in the same game. Their 2026 meeting is scheduled for Lumen Field.
Why it matters: The pairing expands a program that initially featured only the home club’s alternate design. Both uniforms entered the rotation last season and remain eligible through 2028.
By the numbers: Los Angeles debuted its Rivalries set on Nov. 16, 2025; Seattle followed on Dec. 18. Both debuts came against each other, 32 days apart.
What to watch: The Rams’ dark design and Seattle’s wolf-grey set will share the field on Christmas Day.
