Carrie Underwood returns this Fall as the voice of NFL's game kickoff, 'Waiting All Day for Sunday Night,' but she won't be doing it alone. The star will be joined by 11 NFL players for her season debut.

Underwood began her run doing the theme song in 2013, and this year, she's kicking things off right when the Denver Broncos host the Indianapolis Colts on Sept. 7. Underwood's vocals will be heard every Sunday night throughout the 'Sunday Night Football' season. The peak of the season will be during the extra special opening for Super Bowl XLIX on Feb. 1.

In June, 11 NFL players took part in a shoot for the opening with the country star. In addition to Underwood, fans can expect to see New Orleans Saints player Jimmy Graham, San Francisco 49ers quarterback Colin Kaepernick, Luke Kuechly from the Carolina Panthers, brothers Eli Manning and Peyton Manning, Brandon Marshall from the Chicago Bears, Clay Matthews from the Green Bay Packers, Philadelphia Eagles' LeSean McCoy, Philip Rivers from the San Diego Chargers, DeMarcus Ware from the Dallas Cowboys and Russell Wilson of the Seattle Seahawks in the opening segment.

“They might want me to replace Carrie Underwood … out of all the players, I’m definitely the best singer," McCoy says jokingly of their opening performance. Kaepernick, on the other hand, admits he's no country star, saying, “I wasn’t singing, I was just going along with the words…"

'Sunday Night Football' kicks off Sept. 7.
