NFL officials said Friday the league completed its investigation of Bears defensive end Ray McDonald’s domestic- violence incident and ruled he didn’t violate its personal-conduct policy. But the NFL continues to look at his alleged sexual-assault incident.

‘‘We have completed that [domestic-violence] investigation,’’ NFL general counsel Jeff Pash said during the Associated Press Sports Editors meetings. ‘‘[Special counsel for investigations] Lisa [Friel] and her team completed that investigation [and] did not establish a violation of the personal-conduct policy. We informed the player and the [NFL] Players Association.’’

McDonald was arrested Aug. 31, 2014, on suspicion of felony domestic violence in San Jose, California, but no charges were filed because of insufficient evidence. Pash said McDonald was informed of the NFL’s ruling a few weeks ago.

Friel, though, said the NFL’s investigation continues into McDonald’s alleged sexual-assault incident. San Jose police began that investigation Dec. 16, 2014, after a hospital reported a possible victim. McDonald hasn’t been charged, but the incident prompted the San Francisco 49ers to release him.

The Bears signed McDonald last month to a one-year, $1.05 million contract that doesn’t include any guaranteed money. It was a signing chairman George McCaskey initially rejected after reviewing McDonald’s case.

‘‘Just to be clear, Ray McDonald had two issues, as you may remember — one related to a domestic-
violence incident and one related to an alleged sexual assault,’’ said Friel, the former head of the Sex Crimes Prosecution Unit in the New York County District Attorney’s Office. ‘‘It’s the domestic-violence incident that we have finished investigating and didn’t find sufficient evidence to say that he violated the personal-conduct policy.

‘‘The sexual-assault incident, that investigation is ongoing. That has not been completed, nor has the district attorney’s office in Santa Clara County completed their investigation into that matter.’’
