49ers Add D.J. Humphries, Eye Defensive Moves

The San Francisco 49ers have signed veteran left tackle D.J. Humphries to strengthen their offensive line after losing backup Jaylon Moore to the Kansas City Chiefs and not drafting a tackle in 2025. Humphries, a 2015 first-round pick and 2021 Pro Bowler, offers valuable experience but is recovering from a late-2023 ACL tear after limited play with the Chiefs last year. The move addresses depth concerns at tackle, especially with star Trent Williams aging and often injured. The 49ers hope an additional offseason will help Humphries return to top form. Meanwhile, rookie safety Malik Mustapha may miss significant early time due to injury, prompting the team to consider signing veteran Julian Blackmon from the Colts. These changes reflect San Francisco's efforts to reinforce protection for quarterback Brock Purdy and bolster defensive depth ahead of the new season.
