On a 4th & 13 at the Cardinals 47-yard line, the Panthers were forced to punt. Patrick Peterson returned the ball into the endzone for an 89-yard touchdown return. With 1:19 left, 4th and 5, at the Cardinals 6-yard line, game on the line, Cam Newton threw a short 4-yard pass to Mike Goodson which wasn't enough for the Panthers despite an amazing debut by Panthers rookie QB Cam Newton. With the loss the Panthers fell to 0-1 and lost their 3rd consecutive regular season opener.
