In addition to Minshew, the team also placed running back Ryquell Armstead, tight end Charles Jones, receiver Michael Walker and safety Andrew Wingard on the list. A player doesn't have to test positive for the coronavirus to be placed on the list; he also could be quarantined after being around an infected person.
NFL teams are not permitted to disclose results of virus tests. Minshew, Walker and Wingard share an apartment together.
The Jaguars had activated Jones from the reserve/COVID-19 list earlier Sunday but placed him back on it in the afternoon.
The Jaguars have announced Minshew as their starter in 2020 after he threw for 3,271 yards and 21 touchdowns with six interceptions as a rookie in 2019. Minshew, a sixth-round pick out of Washington State, led the Jaguars to a 6-6 record.
