A quartet of Seahawks 2019 NFL Draft picks have been placed on the preseason physically unable to perform list, or PUP, ahead of the start of training camp next week.

The four rookies are:

• Safety Marquise Blair, Seattle’s second-round pick out of Utah

• Guard Phil Haynes, a fourth-round selection from West Virginia

• Linebacker Ben Burr-Kirven, a fifth-round pick who starred for the UW Huskies

• Defensive tackle Demarcus Christmas, who the Seahawks took in the sixth round out of Florida State.

Additionally, the Seahawks place offensive lineman Demetrius Knox, a rookie signed as a free agent, on the non-football injury list.

Placing players on the preseason PUP list shouldn’t be all that concerning, but rather is an indication that a player is dealing with some type of injury that the team could foresee requiring them to miss time between now and the start of the regular season. Players that are placed on the preseason PUP can come off the list at any time, but players cannot be added to the PUP during training camp.

Blair had a hamstring injury during Seattle’s offseason program, while hernia surgery kept Burr-Kirven out of action during OTAs.
