Carrie Underwood did not score a touchdown when she sang the Sunday Night Football theme song on — you guessed it — this past Sunday night (September 9).

The country star, who has sung "Oh, Sunday Night" since 2014, debuted a brand new theme song for the NBC sports program this weekend, called "Game On."

Listen, below:

The new version, which was played before the game between the Chicago Bears and Green Bay Packers, finds Underwood singing "Game On” instead of “Ohhhhhhh, Sunday night," a line many fans have grown to love over the last four years. Some were downright pissed about the change — and they let Underwood and the NFL know it on Twitter.

See some of their incensed reactions, below:

In 2013, Underwood took over singing the theme from Faith Hill, who performed previous theme song, "Waiting All Day for Sunday Night." The song has also been performed by Pink.

Underwood's new album, Cry Pretty, is out September 14.
