NFL reporter Dianna Russini has resigned from The Athletic less than a week after photographs of her with New England Patriots head coach Mike Vrabel prompted an internal investigation at the New York Times-owned sports publication.

The photos, which showed Russini and Vrabel at an Arizona resort, were published by the New York Post's Page Six and were reportedly taken before the NFL owners meetings that began in Phoenix on March 29.

The Athletic launched an investigation into Russini's conduct following the publication of the photographs. The nature of the investigation and specific concerns about the photos have not been publicly detailed by the publication.

Russini was considered one of the NFL's top reporters and had been a prominent figure in sports journalism. Her resignation came within days of the photos surfacing and the subsequent internal review.

The Athletic, which was acquired by The New York Times, has not provided additional details about the investigation or the circumstances surrounding Russini's departure from the organization.
