Now, Hundley is presumably just extra quarterback insurance in case either starter Carson Wentz or backup Sam Ehlinger ends up on the Reserve/COVID-19 list and are forced to miss this weekend’s game against the Arizona Cardinals (which cannot be completely ruled out given the current climate of the pandemic).
