1928 Idaho Vandals football team

The 1928 Idaho Vandals football team represented the University of Idaho in the 1928 college football season. The Vandals were led by third-year head coach Charles F. Erb and were in their seventh season in the Pacific Coast Conference. Home games were played on campus in Moscow at MacLean Field. Idaho compiled a 3–4–1 overall record and went 2–3 in conference games.

In their first year in the conference,^[1] UCLA traveled to Moscow in late October and fell, 20–6.^[2][3] It was UCLA's only loss in the seven-game series; the teams have not met since 1948. Idaho's only other win over a PCC team from the state of California came in 1947 at Stanford.^[4]

The week after the win over UCLA was the Battle of the Palouse with neighbor Washington State,^[5] and the visiting Cougars inflicted a 26–0 homecoming shutout before 10,000;^[6] the teams had tied the previous season in Pullman.^[7][8] Prior to the start of the game, the new Memorial Gymnasium was presented to the university;^[6] the venue honors state residents who gave their lives in the service of their country in World War I.^[9][10][11]

Amid speculation about his future at Idaho,^[12] Erb resigned on December 22, four weeks after the season's completion.^[13] He was succeeded by Leo Calland, a USC assistant coach and former player for the Trojans.^[14][15]
