Detectives have determined what caused Tiger Woods to crash his car last month in southern California, according to the Los Angeles County sheriff.
However, they would not release details, citing unspecified privacy concerns for the golf star.
Woods suffered serious injuries in the February 23 crash, striking a raised median just outside Los Angeles at around 7am.
The SUV he was driving crossed through two oncoming lanes and uprooted a tree on a downhill stretch that police said is known for wrecks.
Woods is in Florida recovering from multiple surgeries.
Sheriff Alex Villanueva has been criticised for his comments about the crash, calling it "purely an accident" and saying there was no evidence of impairment.
Woods told deputies he did not know how the crash occurred and did not remember driving.
Investigators did not seek a search warrant for Woods' blood samples, which could be screened for drugs and alcohol.
In 2017, Woods checked himself into a clinic for help in dealing with prescription drug medication after a DUI charge in his home state of Florida.
Detectives, however, did obtain a search warrant for the data recorder of the 2021 Genesis GV80 SUV, known as a black box.
Mr Villanueva would not say what data had been found in the black box. "A cause has been determined, the investigation has concluded," he said during a live social media event yesterday.
Mr Villanueva claimed that investigators needed permission from Woods - who previously named his yacht Privacy - to release information about the crash.
"We have reached out to Tiger Woods and his personnel," Mr Villanueva said.
"There's some privacy issues on releasing information on the investigation, so we're going to ask them if they will waive the privacy and then we will be able to do a full release on all the information."
Mr Villanueva's statement about privacy issues did not make sense to Joseph Giacalone, a professor at the John Jay College of Criminal Justice and a retired New York City Police Department sergeant, who has criticised the sheriff's response to the Woods incident from the start.
"I don't think I've ever seen a department ever ask for permission like that," he said. "What happens if his lawyers say 'No, you can't send it out now.' Where does that leave us?"
Mr Giacalone said it was unlikely that deputies would have sought the permission of non-celebrity victims in similar crashes to release information.
