An unidentified woman has been taken away in an ambulance from a house on the street in Florida where golfer Tiger Woods lives, reports say.
Local television stations in Orlando said a call for an ambulance had been received from Woods' home in the gated Isleworth community at 0236 (0736 GMT).
TV footage showed a woman being wheeled on a stretcher into a nearby hospital.
Last week, Woods apologised to his family for letting them down amid speculation about his private life.
The statement came days after he was found bleeding and semi-conscious after his car hit a tree and fire hydrant outside his home, and followed a story in a US gossip magazine that he had had a 31-month affair with a Los Angeles cocktail waitress.
Woods was later charged with careless driving and fined $164.
The 14-time major champion has been married to his Swedish wife Elin, a former model, for five years. The couple have two children.
On Tuesday morning, a spokeswoman for the Orange County Fire Rescue service told the Associated Press that medics had responded to an overnight 911 emergency call from Deacon Circle in Isleworth, and that an adult had been taken to hospital.

But she would not say whether the call had come from Tiger Woods' home, or if the person who received treatment had been a woman.
The Orlando television station, WESH, reported earlier that a radio log showed an adult woman had been transported from Woods' home to the Health Central Hospital in nearby Ocoee.
The log showed the patient had initially refused transport, but was later listed as an advance life support patient, it added.
WESH said the video from the hospital showed a blonde woman being taken through the entrance to the emergency room.
A black Cadillac Escalade, with a number plate similar to the one involved in Woods' car crash, was reportedly seen at the hospital.
The information has not been independently confirmed.
