The Seahawks made five health-related roster moves Wednesday as rookies officially reported for training camp.
Four rookies — all draft picks — were placed on the physically unable to perform (PUP) list: linebacker Ben Burr-Kirven, safety Marquise Blair, defensive tackle Demarcus Christmas and guard Phil Haynes.
Additionally, undrafted free agent rookie offensive lineman Demetrius Knox was placed on the non-football injury list.
Players can be activated off the preseason PUP list at any time, so this designation does not necessarily mean any of their injuries are serious. But players cannot go on the preseason PUP list once camp begins, so placing them on it now gives the team some potential roster flexibility down the road in case any of the injuries linger, or players have setbacks.
