San Francisco 49ers face injuries and coaching recovery

The San Francisco 49ers are managing various injuries and personnel updates following their preseason opener against the Tennessee Titans. During the game, third-string quarterback Kurtis Rourke was hospitalized with a rib injury after experiencing shortness of breath, though he has since been released.

In coaching news, head coach Kyle Shanahan is recovering from a severe concussion sustained in a car accident in July. Shanahan noted that the experience has increased his understanding of the physical and mental toll of concussions on players.

On the field, wide receivers Jacob Cowing and Mike Evans have returned to practice, while running back Christian McCaffrey and defensive end Nick Bosa remain sidelined with minor issues. Additionally, a sideline moment involving George Kittle and Mac Jones using smelling salts has gained social media attention, though the use of such items is permitted by the league if brought by players personally.
