The San Francisco 49ers announced on Wednesday that they’ll wear their new white throwback uniform Week 7 when they host the Los Angeles Rams on Sunday Night Football. The 49ers introduced the new uniforms earlier this offseason to replace the black alternates they used the past three seasons.

It is fitting the 49ers will wear the uniforms against the Rams. While teams like the Seahawks, Cowboys, and Packers have offered more intense rivalries over the years, the Rams represent their “longest” rival. The two sides have squared off 136 times over the years. The next closest are the Atlanta Falcons (77 games) and New Orleans Saints (75 games) from the old structure of the NFC West.
