Overview

• Drake Jackson, the 49ers' 2022 second-round draft pick, was waived with a failed physical designation after missing 1 1/2 seasons due to a torn patellar tendon.
• Jackson’s release clears the way for rookie Mykel Williams, drafted 11th overall in April 2025, to start alongside Nick Bosa on the defensive line.
• The 49ers bolstered their depth by signing offensive linemen Andre Dillard and Nicholas Petit-Frere, as well as cornerback Dallis Flowers, all on one-year contracts.
• Jackson initially showed promise with three sacks in the 2023 season opener but failed to record any additional sacks before his injury later that year.
• The roster overhaul reflects the team’s focus on strengthening its defensive front and addressing gaps ahead of the upcoming NFL season.
