Scandal-hit Tiger Woods has decided to take an "indefinite break" from golf after admitting his infidelity for the first time.

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.

In a statement on his official website, www.tigerwoods.com, the champion golfer said: "After much soul searching, I have decided to take an indefinite break from professional golf."

The accident left him needing hospital treatment and immediately raised questions over the circumstances which preceded it.

It has been speculated that reports of an affair with New York socialite Rachel Uchitel led to a confrontation with his wife shortly before he got into his SUV that morning.

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.

"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. Again, I ask for privacy for my family and I am especially grateful for all those who have offered compassion and concern during this difficult period."
