Schrauth (knee) did not participate in Tuesday's practice, Greg Auman of Fox Sports reports.
Schrauth sprained his knee in early August. The guard remains sidelined with a brace, and it is unclear when he will return to the field. The rookie fifth-rounder will not have much time to make his case for the 53-man roster once he regains his health, so he is a strong candidate for season-ending injured reserve.
