San Francisco 49ers sign Dimukeje and Zakelj, release Khalil Herbert

The San Francisco 49ers have made several roster adjustments ahead of their preseason matchup against the Los Angeles Chargers. The team signed defensive lineman Victor Dimukeje and offensive lineman Nick Zakelj to one-year deals. Zakelj returns to the roster after being released earlier in the week.

To facilitate these signings, the 49ers released running back Khalil Herbert and offensive lineman Kion Smith. The departure of Herbert comes amid depth concerns in the running back room, as several players including Kaelon Black and Jordan James are currently managing injuries.

With Christian McCaffrey being managed cautiously due to minor tightness, the team's backfield depth remains a focal point as they approach the final preseason game and the transition to the 53-man roster.
