It's no secret that football is king in this country, especially on Sundays, even if Game 5 of a competitive World Series knotted at two games apiece is going head-to-head with the NFL.

The Kansas City Chiefs-Green Bay Packers matchup on NBC's "Sunday Night Football" had a 61 percent viewership advantage over the Houston Astros-Washington Nationals contest on Fox, according to NBC Sports, the largest margin between a "Sunday Night Football" game and a World Series televised at the same time.

According to Sports Media Watch, the football game drew 18.32 million viewers.

The Chiefs were playing without MVP Patrick Mahomes and instead had Matt Moore starting at quarterback, while Aaron Rodgers and the Packers outlasted the Chiefs 31-24 in a game that came down to the final possessions.

Meanwhile, Nationals starter Max Scherzer was scratched in the hours before Game 5, depriving fans of a Scherzer-Gerrit Cole pitching duel. Instead, the Astros raced out to a 4-0 lead and kept the Nationals at bay.

MLB will not have to worry about the NFL stepping on its toes for the remainder of the series, as Game 6 will be played Tuesday and Game 7 on Wednesday, if necessary.

Last year, Boston's five-game World Series victory over the Los Angeles Dodgers averaged 14.1 million viewers, down 25 percent from the previous year and the fourth-lowest ever.
