Fox has hinted at keeping its Sunday package with the NFL and dropping Thursday Night Football.

The NFL has had ongoing talks with its media partners over the past few months. The league’s current rights deal with Disney’s ESPN lapses after the 2021 season, while its contracts with the remaining three last through 2022.

“If there is a choice between the two,” said Steve Tomsic, Fox Corp.’s CFO, speaking to investors at a conference organized by UBS, Fox’s Sunday package “is absolutely core to our hearts.” He added: “The heritage of the company was built on Sunday afternoon football.”

CBS, NBC and Fox are believed to be paying a combined $3.1 billion per year for Sunday games, compared to $1.94 billion a year under the previous contract. ESPN’s rights to broadcast “Monday Night Football” are believed to cost around $1.9 billion per year, compared to $1.1 billion paid in the previous contract. Fox struck a separate deal to broadcast “Thursday Night Football” for five years starting in the fall of 2019, a contract believed to be worth more than $650 million per year.
