The Bridgestone was two weeks after Woods fired Williams.
When asked about the interview, Williams replied, "It was my aim to shove it up that black a***hole''.
Williams has denied the comment was racist, saying it was made in jest.
Woods said the comment was hurtful and should not have been made.
"I don't know how it could have happened but it did,'' he said.
"It was hurtful (but) life goes forward.
"We'll see what time does. As we all know, time does heal all wounds.
"Steve's certainly not a racist. It was a comment that shouldn't have been made.''
Williams now caddies for Australian Adam Scott, who defended Williams in a statement yesterday.
"I have discussed this matter directly with Steve and he understands and supports my view on this subject. I also accept Steve's apology, knowing that he meant no racial slur with his comments.
"On behalf of my team, I apologise personally to everyone that was offended by the reported comments,'' he said.
Greg Norman also defended Williams, saying he did not believe he was a racist.
"We've all made stupid comments at stupid times. Unfortunately his stupid comment became global news.
"I know he probably regrets saying it, but I guarantee you in that room on that night there was probably some heavier things said,'' he is reported as saying.
Michael Campbell said the comments were simply "Steve's personality''.
"Is he a racist? No. He's one of my best mates,'' The Herald Sun reported him as saying.
However, not everyone in the golfing world agreed.
Fred Couples said: "If he was my caddie he would be gone by now.
"If he has that sort of anger for a pretty good guy, then I don't want him around me,'' he is reported as saying.
