Seattle Seahawks open their training camp under head coach Mike Macdonald with several key players placed on the physically unable to perform (PUP) list, according to reporting from multiple outlets. The team begins camp while those athletes are not immediately available to participate in full workouts due to ongoing conditions or recovery from injuries. The outlets describe the situation as a standard early-camp roster management approach, where players on PUP remain ineligible for certain on-field activities for a specified period. While specific player names and the reasons for placement are not detailed in the provided excerpts, the coverage consistently indicates that the Seahawks’ camp starts with notable contributors listed on PUP rather than joining team activities from day one. As the training schedule progresses, players on PUP can potentially become available later depending on medical clearance and league rules governing eligibility during camp.
