The 49ers have until 1 p.m. on Saturday to trim the offseason roster to 53 players. Here we’ll track the moves as the news comes down, after they cut 12 players on Friday and traded for Browns offensive lineman Shon Coleman.
--Ian Rapoport of NFL Network reports the 49ers are releasing guard Jonathan Cooper, who signed a one-year, $4.9 million contract in the spring. The former first-round pick of the Cardinals had offseason knee surgery and was slow to work himself back into the fold throughout training camp and the preseason.
Cooper, 28, played a team-high 60 snaps in the exhibition finale on Thursday at left guard.
