Cam Newton was understandably happy after his Carolina Panthers held off the hard charging Seattle Seahawks to advance to the NFC Championship game.

So, after the game he went around to celebrate some with Carolina fans and was handed a Seahawks 12th man flag. His trademark smile briefly left his face, and he was clearly in no mood to receive such an abomination.

This is not the first time this season that Newton has done away with an opposing team’s flag or banner in Carolina. In November, Newton famously took a Green Bay Packers banner that was hanging at Bank of America Stadium down.

So, Arizona Cardinals fans thinking of traveling to Charlotte for next week’s NFC Championship Game beware. If you’re near Cam Newton, keep your flag, sign, or banner hidden, or risk not ever seeing it again.
