49ers' Fred Warner: Activated from COVID-19 list

The 49ers activated Warner from the reserve/COVID-19 list Wednesday, Adam Caplan of SiriusXM NFL Radio reports.

San Francisco still has some injury concerns on offense, but Warner's potential absence to begin the season was the only lingering issue of import on the defensive side. Warner hasn't missed a start since the Niners made him a third-round pick in 2018, with the linebacker piling up 242 tackles (174 solo), 15 pass defenses, four forced fumbles, three sacks and an interception over 32 games and 2,045 defensive snaps. His three-down role and strong work in pass coverage could lead to a big stat line Week 1 against the uptempo Arizona offense.
