The N.F.L. did not interview Hunt because none of the alleged victims would speak to the league. Instead, the league relied on the Chiefs, who were told by Hunt that no violence had occurred, according to a person briefed on the investigation who was not authorized to discuss its specifics.

Hunt was involved in another violent episode in May, when he punched a man in the face, but again, the police did not file charges, and the Chiefs took no action against him.

Also last week, Reuben Foster, a linebacker, was released by the San Francisco 49ers after being arrested on domestic violence charges, but was then almost immediately hired by the Washington Redskins. Foster is suspended from play and practices but can work out and attend team meetings.

Doug Williams, the former player and current Redskins executive, was roundly criticized when he described Foster’s arrest as “small potatoes” in a radio interview. He later apologized.
