The 49ers waived defensive lineman Evan Anderson in July, but they brought him back to the team on Tuesday.
They announced Anderson's signing and created space for him on the active roster by waiving defensive lineman Titus Leo. Leo was let go with an injury designation.
Anderson signed with the 49ers after going undrafted in 2024 and he played in 12 games during his rookie season. He failed to make the cut to 53 players last summer and spent the regular season on the practice squad.
Anderson had 24 tackles, a sack, a forced fumble and a fumble recovery during his first run with the team.
