Shaheed (knee) didn't practice Friday, John Boyle of the Seahawks' official site reports.
Shaheed suffered a knee injury in the first half of this past Sunday's win against the Chiefs and wasn't able to return. Since then, head coach Mike Macdonald told Brady Henderson of ESPN.com that the "early returns are positive" on Shaheed, but with no on-field work yet this week he likely will need to mix into drills Saturday to have a chance to play Monday versus the Bears.
