Sun Devils coach Kenny Dillingham told reporters that Rashada, who did not play in Saturday's 29-0 loss to Fresno State, is expected to miss four to six weeks with an injury that has bothered the freshman since he was in high school. Dillingham did not specify other details about the injury.
Trenton Bourguet, who started Saturday against the Bulldogs, left after two drives with a foot injury. Dillingham said Bourguet will have an MRI.
Dillingham left open the possibility of redshirting Rashada, the No. 27 overall recruit in the 2023 class who played in the first two games of the season after winning a camp battle to be starting quarterback.
Arizona State (1-2) was shut out for the first time since 2008 and the first time at home since 1988. The Sun Devils open Pac-12 play Saturday against No. 5 USC.
