The Cardinals suffered a 22-16 loss to the Seahawks on Thursday in Glendale.
In a historic game for Cardinals receiver Larry Fitzgerald, head coach Bruce Arians failed to register his first win over the Seahawks at University of Phoenix Stadium.
Arizona scored a late touchdown with 20 seconds left on a 1-yard run by Andre Ellington, but the extra point was blocked. The ensuing onside kick was unsuccessful.
The other scoring from the Cardinals came via a 9-yard pass from Drew Stanton to tight end Jermaine Gresham and a mid-range field goal by Phil Dawson.
