Junior quarterback Tommy Armstrong will not play in the Huskers' football game at Purdue on Saturday.
Mike Riley made the announcement following Thursday's practice. Armstrong, who was hobbled after a low hit on Nebraska's last drive against Northwestern last week, watched Thursday's practice in sweats and had a walking boot on his right foot.
Grand Island graduate Ryker Fyfe will make his first career start when the Huskers travel to West Lafayette.
Riley also announced that starting safety Byerson Cockrell, who leads the team in tackles, will miss Saturday's game to attend a family funeral.
