Overview
- San Francisco agreed Friday to a one-year contract with Jack Jones, which his agent confirmed after a visit to the team facility.
- Jones is expected to compete as outside depth behind starters Deommodore Lenoir and Renardo Green in a scheme that leans on press coverage.
- He started all 17 games for the Dolphins in 2025 and led Miami cornerbacks in snap share at about 91%, finishing with 77 tackles, six pass breakups, two forced fumbles and one interception.
- Across four NFL seasons, he has eight interceptions and four pick-sixes, which ranks near the top in that span for interception-return touchdowns.
- Analysts say his arrival could squeeze the depth chart, with one projection noting Darrell Luter Jr. may be at risk if the 49ers do not draft a corner.
