'This situation is my fault and it's obviously embarrassing to my family and me,' he said on his website yesterday. 'I'm human and I'm not perfect. I will certainly make sure this doesn't happen again.'
Following stories that he fought with wife Elin Nordegren after a US magazine reported he had had an affair with Rachel Uchitel, Tiger wrote: 'This is a private matter.'
He slammed any talk of an affair as irresponsible 'false, unfounded and malicious rumours'.
'My wife, Elin, acted courageously when she saw I was hurt and in trouble. She was the first person to help me. Any other assertion is absolutely false,' he added.
A tape has been released of the emergency call made on Friday, when Tiger was found unconscious outside his car.
