NEW YORK — A person with knowledge of the decision says NBC Sports Group Chairman Dick Ebersol has resigned.

The person said Thursday that the move was because of a contract dispute and did not involve the network’s negotiations with the International Olympic Committee over the broadcasting rights for upcoming games under its new partnership with Comcast.

The person spoke on condition on anonymity because the resignation had not yet been announced. Ebersol’s decision was first reported by The New York Times.

In 1975, as NBC’s director of weekend late night programming, Ebersol and Lorne Michaels conceived and developed “Saturday Night Live.” Ebersol returned to the network as president of NBC Sports in 1989.
