SEATTLE -- Cam Newton threw a 26-yard touchdown pass to Greg Olsen with 32 seconds left and the Carolina Panthers remained unbeaten, rallying for a stunning 27-23 win over the Seattle Seahawks on Sunday.

Newton led the Panthers (5-0) to touchdowns on their final two possessions after trailing 23-14, the second straight week the Seahawks collapsed in the fourth quarter. Newton found Olsen wide open down the seam as All-Pros Earl Thomas and Richard Sherman looked at each other in confusion.
