After the Carolina Panthers beat the Seattle Seahawks in the divisional round of last year's playoffs, quarterback Cam Newton ran around Bank of America Stadium high-fiving fans.

But when one Seahawks fan dangled a "12" flag near Newton, he grabbed it, crumpled it up and tossed it -- all with a smile on his face.

As the Seahawks prepare to host the Panthers on Sunday night, cornerback Richard Sherman was asked if Newton crossed the line with his gesture.

"Yeah, he probably did," Sherman said. "I guess karma gets you. It doesn't look like you're going to be in the playoffs this year."
