Underwood has performed the opening theme song for "NBC Sunday Night Football" since 2013. Faith Hill later expressed full support for Underwood, congratulating her via Twitter and stating that it was "an awesome choice" by NBC/SNF and that Underwood "will rock it". Underwood's original song was a modification of her song "Oh, Sunday Night", but was changed to an original song, "Game On", for the 2018 NFL season. She sang the National Anthem for the Nashville Predators prior to their victory over the Chicago Blackhawks in Game 3 of the first round of the 2017 Stanley Cup Playoffs and prior to their victory over the Winnipeg Jets in Game 2 of the second round of the 2018 Stanley Cup Playoffs.
