Shaheed (knee) is listed as out for Sunday's game against the Cardinals, Gregg Bell of 933 KJR reports.
With Shaheed out last week, Tory Horton handled a 72 percent route share in Seattle's loss to Chicago. It'll likely be a similar look this week with Horton and Cooper Kupp taking most of the WR snaps alongside Jaxon Smith-Njigba. The big difference will be under center, where Drew Lock is filling in for Sam Darnold (quad) for the second time this season.
