As the Carolina Panthers get ready for Sunday's crucial NFC South tilt with the rival Atlanta Falcons, a few familiar backfield mates warmed up the pipes.

The trio of Christian McCaffrey, Fozzy Whittaker and Jonathan Stewart gave it their all in serenading one fan from California, flown in for the game by the Roaring Riot fan club, in a rendition of Bill Withers' "Lean on Me".

The Panthers' kickoff is set for 1 p.m. ET on Sunday, at Bank of America Stadium in Charlotte.
