The latest NFL season is only a week away and a new season of 'Sunday Night Football' kicks off next weekend (Washington vs Dallas) with a bevy of changes, the biggest of which may be Carrie Underwood replacing Faith Hill performing the iconic 'Sunday Night Football' theme.

In this behind the scenes video, you'll see Underwood's rehearsals, her interaction with a number of NFL stars (who seem a bit overwhelmed in her presence) and a sneak peek at the new opening number starring Underwood, plus superstars Peyton and Eli Manning, Aaron Rodgers and Larry Fitzgerald.
