Rasul Douglas corralled an interception with 12 seconds left in the fourth quarter that helped the Packers knock off the previously unbeaten Arizona Cardinals 24-21 in a thriller that featured two of the NFL's top quarterbacks.

The Cardinals looked like they were going to rally to win their eighth straight game but Kyler Murray threw the stunning interception on second-and-goal as the home crowd groaned in disbelief. A.J. Green didn't expect the pass to come his way, never turned around and Douglas was there to snatch the ball in the corner of the end zone.

Green Bay grabbed a 10-7 halftime advantage by making a field goal after Cardinals rookie Rondale Moore mishandled a punt deep in Arizona territory.

Early in the third quarter, Murray threw a pass that was deflected by Moore into the hands of Green Bay's Henry Black at the Arizona 14. Five plays later, Rodgers found Cobb in the corner of the end zone for a touchdown and 17-7 lead.

The Cardinals responded, but fell just short of the win. Murray finished with 274 yards passing and two interceptions.
