Ben Roethlisberger and three others have been added to the Pittsburgh Steelers' reserve/COVID-19 list.

The unbeaten Steelers confirmed on Tuesday that quarterback Roethlisberger, offensive lineman Jerald Hawkins, running back Jaylen Samuels and linebacker Vince Williams are isolating for at least five days.

The quartet are permitted to take part in virtual meetings and must test negative before they can be considered for Sunday's game against the Cincinnati Bengals at Heinz Field.

The announcement was made a day after tight end Vance McDonald was placed on the list after testing positive for the virus.

The Steelers defeated the Dallas Cowboys 24-19 to move to 8-0 at the top of the AFC North on Sunday.
