PROVO, Utah-Per a Tuesday announcement from the BYU athletics department, the school’s football team will wear throwback uniforms against No. 21 Washington Saturday at LaVell Edwards Stadium.

The Cougars are doing this to honor college football’s 150th anniversary.

Fans attending Saturday’s game are encouraged to wear white shirts for a “whiteout” at the stadium.

This means the Cougars will wear “history-inspired” retro white and royal uniforms, including a special throwback helmet design featuring the original block “Y” worn by the football team.

The helmet will also only feature a single royal blue center stripe and gray face mask comparable to those used by the Cougars in the 1950’s and 1960’s.

The jerseys will be white with blue numerals and royal trim, as well as royal pants. The Cougars will also don blue double-striped white socks worn during the 1970’s.

Additionally, the field at LaVell Edwards Stadium will feature a retro scheme with painted end zones featuring a diamond-shaped pattern used in the 1960’s along with a midfield logo of the special throwback helmet the Cougars will wear for this game.

Cougars greats of the past will be honored, including 1990 Heisman Trophy-winning quarterback Ty Detmer, and Outland Trophy winners Mo Elewonibi (1989) and Jason Buck (1986) as well as former star safety Derwin Gray (1989-1992).
