The San Francisco 49ers have placed linebacker Fred Warner on the reserve/COVID-19 list.
Warner being added to the list means he has either contracted COVID-19 or come into contact with a person who has tested positive.
A third-round pick in 2018, Warner has become an integral part of a 49ers defense that was among the best in the NFL last season.
He finished the regular season with 118 tackles, three sacks, three forced fumbles and an interception returned for a touchdown as the 49ers topped the NFC with a 13-3 record.
San Francisco then progressed to Super Bowl LIV, with Warner intercepting Patrick Mahomes in the 49ers’ 31-20 defeat to the Kansas City Chiefs in February.
