Scandal-hit Tiger Woods said he was taking an "indefinite break" from golf as he apologised for his "infidelity".
Posting a message on his website, the champion golfer said: "After much soul searching, I have decided to take an indefinite break from professional golf."
He added: "I am deeply aware of the disappointment and hurt that my infidelity has caused to so many people, most of all my wife and children. I want to say again to everyone that I am profoundly sorry and that I ask forgiveness."
The 33-year-old, who is married to Swedish former model Elin Nordegren, has been swamped by a series of affair allegations since crashing his car in mysterious circumstances on November 27.
Woods continued: "It may not be possible to repair the damage I've done, but I want to do my best to try.
"I would like to ask everyone, including my fans, the good people at my foundation, business partners, the PGA Tour, and my fellow competitors, for their understanding.
"What's most important now is that my family has the time, privacy, and safe haven we will need for personal healing.
"I need to focus my attention on being a better husband, father, and person."
The number of women who have come forward with claims of a sexual involvement with the billionaire sportsman stands in double figures.
The allegations have caused headlines around the world and affected Woods' previously wholesome family image.
