Ross missed practice Tuesday and there's no timetable for his return, according to NFL Network's Tom Pelissero. He's expected to be placed on the reserve/COVID-19 list.
The Bengals drafted Ross ninth overall in 2017. He's amassed 49 receptions for 716 yards and 10 touchdowns through 24 career games.
Cincinnati declined the fifth-year option on Ross' rookie contract this offseason.
