Key losses
OT Joe Staley
Day 3 of the 2020 draft was a significant day in 49ers history. Staley officially announced his retirement shortly after the team announced a trade for seven-time Pro Bowl left tackle Trent Williams. The 49ers will go into the year with a new left tackle for the first time since 2007 when Staley was drafted in the first round.
OL Mike Person
Staley wasn’t the only starter the 49ers lost on the offensive line. They also released their starting right guard. Person held that job for the last two seasons, but a neck injury toward the end of last year sidelined him for two games. San Francisco released him before the start of the 2020 league year. Person later announced his retirement after seven NFL seasons.
DB DJ Reed
The 49ers probably didn’t anticipate losing Reed this offseason. He suffered a season-ending pectoral tear in a workout while away from the team. They waived him with the likely hope he’d clear waivers and revert to their Injured Reserve. Seattle claimed him instead.
