Jimmie Johnson helps Carolina Panthers to 'Keep Pounding'

6-time NASCAR champion Jimmie Johnson was swinging a big stick at Bank of America Stadium on Sunday. 

Johnson was on hand to beat the Carolina Panthers "Keep Pounding Drum" before the team's tilt with the Tampa Bay Buccaneers. Before every home game, an honorary drummer hits the drum four times to signify four quarters.

"Keep Pounding" is the motivational mantra of the late Panthers player and coach Sam Mills. Johnson proved to be a good luck charm, as the Panthers topped the Bucs 19-17.
