Panthers tight end Greg Olsen caught a 26-yard touchdown with 32 seconds left in the fourth quarter to upend the Seahawks 27-23 on Sunday.
Carolina (5-0) trailed by nine points with under 10 minutes to go in the fourth quarter, but Cam Newton — who had struggled throughout the game — led the Panthers to an improbable win in Seattle.

Newton finished the game 20 of 36 for 269 yards and accounted for two touchdowns (one rushing), but also threw two interceptions. Olsen caught seven passes for 131 yard and a touchdown.
The Seahawks have now blown big leads in the fourth quarter two weeks in a row. Last week, it was a 17-point lead, which ultimately led to an overtime loss to the Bengals. This is starting to become a trend for Seattle's vaunted Legion of Boom defense, which has blown 14 fourth-quarter leads since 2012 under coach Pete Carroll.
Seahawks fans did get a boost when Marshawn Lynch returned from a nagging hamstring injury, making his first start since Week 3 against the Bears.
Lynch rushed 17 times for 54 yards and a touchdown.
