Overview
- The 49ers announced on Tuesday that they signed Ashtyn Davis to a one-year deal and waived running back Jermar Jefferson to open a roster spot.
- Davis is a 29-year-old Santa Cruz native who was a third-round pick in 2020 and has six NFL seasons of experience with the Jets and Dolphins.
- In 2025 with Miami he started 12 games, registered 63 tackles and one interception, and also has 23 career special-teams tackles that add immediate depth on kick coverage units.
- Jefferson had joined San Francisco on May 28 and is now off the roster, a quick turnover that reflects normal offseason evaluation and creates a hole among reserve running backs.
- This move tightens the 49ers’ defensive backroom and boosts competition for safety snaps while giving the team a veteran who can play deep safety, slot alignments, and contribute on special teams ahead of training camp.
