The San Francisco 49ers have placed linebacker Fred Warner on the reserve/COVID-19 list.

Warner didn’t practice on Sunday and then was placed on the COVID-19 list the following day. The list is used for NFL players who either test positive for the coronavirus or have been in close contact with an infected person.

Warner is the third 49ers player to be placed on the list this summer. Receiver Richie James Jr. and running back Jeff Wilson Jr. each had short stints on the list early in training camp.
