Shaheed (knee) did not practice Wednesday, John Boyle of the Seahawks' official site reports.
Shaheed missed Monday night's loss to the Bears, which allowed Tory Horton to log a season-high 43 offensive snaps, which he turned into a 3-26-0 receiving line on six targets. Horton would again be in line for WR3 duties if Shaheed needs to sit Sunday against Arizona.
