On Dec. 11, Woods announced that he will take an "indefinite" leave from professional golf to spend more time to save his family.

He had undergone 45 days of therapy and prepared for further treatment, according to the statement.

In addition, Woods denied speculations that Elin Nordegren, his wife, had attacked him on Thanksgiving night, which is reported to be the cause of his car crash.

"Elin has never hit me that night or another night. There has never been an issue of domestic violence in our marriage," he said, adding that he is "the only person to blame."

Once seen as a squeaky clean athletic role model, Woods, 34, has been tainted by allegations of serial infidelities with as many as 10 women around the United States including various waitresses, nightclub hostesses and porn stars.

Woods has had a phenomenal career, earning more than 1 billion U.S. dollars in his rapid 13-year rise, commanding huge fees for sports endorsements and revolutionizing sports marketing.
