The San Francisco 49ers' training camp faced a setback as seven players were absent from the sixth practice due to injuries, notably rookie Mykel Williams, who is dealing with a minor ankle injury. Williams had started impressively, playing on the first-team defensive line. Other significant absentees include cornerbacks Deommodore Lenoir and Renardo Green, both of whom are dealing with injuries, raising concerns about the depth in the secondary. Running back Jordan James and wide receiver Ricky Pearsall were also sidelined, with Pearsall's absence being a precautionary measure as he recovers from a prior hamstring injury. Additional players missing practice included Jacob Cowing, dealing with a hamstring issue, and Jauan Jennings, who has a calf injury.
