The Ravens also designated DB Terrell Bonds to return from injured reserve.
The COVID-19 list was created this summer for a player who either tests positive for or who has been quarantined after having been in close contact with an infected person or persons.
Players will remain on the list until they are medically cleared to return.
Brown, 23, is a former first-round pick of the Ravens back in 2019. He’s currently in the second year of his four-year, $11.8 million contract.
The Ravens have a fifth-year option to pick up on Brown in 2022.
In 2020, Brown has appeared in 13 games for the Ravens and caught 43 passes for 605 yards receiving and five touchdowns.
