49ers face QB Purdy uncertainty and roster changes amid injury concerns

San Francisco 49ers' QB Brock Purdy is unlikely to play in Week 2 due to a toe and shoulder injury, with the possibility of missing multiple games. The team is considering adding another quarterback, potentially Mac Jones, while preparing to start with Jordan Jones if needed. Several other players are also dealing with injuries, but Jauan Jennings may return for the game against the New Orleans Saints.
