PONTE VEDRA BEACH, Fla. - Tiger Woods publicly apologised Friday without revealing any new details about his infidelity, and told a global audience he's not sure when he'll play golf again. Speaking before a small group at the TPC Sawgrass clubhouse and a massive television audience, one of the world's most-recognized athletes repeatedly told his family, sponsors and fans; in essence, everyone connected with him; that he was sorry for behavior. "I was unfaithful. I had affairs. I cheated. What I did was not acceptable," said Woods, looking composed and speaking in a steady voice. His wife, Elin, was not with him. As for coming back to the PGA Tour, Woods said: "I do plan to return to golf one day. I just don't know when that day will be. I don't rule out it will be this year." Like Woods' career itself, the event demanded attention. The golfer talked for 13 1/2 minutes at the clubhouse, home of the PGA Tour. About 40 people were in the room, including his mother in the front row. All sat quietly as Woods, a billion-dollar brand, spoke from behind a podium backed by a blue curtain. When he finished, Woods hugged his mother and she whispered in his ear. "I said 'I'm so proud of you. Never think you stand alone. Mom will always be there for you and I love you,'" Kultida Woods said.
