Fox Corp. said Thursday that it wouldn't amend its existing rights deal to broadcast National Football League games until after 2029, the media company's Chief Executive Lachlan Murdoch told investors on the company's earnings call.

In recent months, the league had indicated that it wanted to renegotiate its rights deals a few years ahead of the window that allows them to do that. Fox has had constructive discussions with the league, and will maintain its current deal and pricing until the 2030 season, Murdoch said.

Fox's announcement comes after relations between Fox and the NFL had frayed over the league's decision to sell rights of its games to streaming services like Amazon's Prime Video and Netflix.

Fox Chairman Emeritus Rupert Murdoch raised concerns about the damage to broadcast networks such as Fox if more NFL games migrate to streaming, The Wall Street Journal has reported. And the Justice Department opened an investigation into whether sports leagues should continue to enjoy antitrust protections under the 1961 Sports Broadcasting Act, which allows them to collectively negotiate television rights on behalf of teams.

An NFL spokesman declined to comment.

Fox said on its earnings call that it expects its deal to buy streaming platform Roku will close in the first half of next year.
