San Francisco 49ers fans received mixed injury updates as training camp progresses. Ricky Pearsall returned to practice, easing concerns about his previous injury, while Kyle Shanahan noted a cautious approach with limited snaps to prevent re-injury. Additionally, special teams will see competition with Pearsall's potential return role. However, Jawan Jennings is dealing with a calf injury that could hamper his start to the season, necessitating careful management. Also, Ronaldo Green's hamstring injury raises questions about the cornerback depth. The 49ers will need to monitor these developments closely as the preseason approaches.
