DO NOT USE

(CBS)  Repentant Miami Dolphins running back Ricky Williams has lived in a tent community in Australia, studied holistic medicine in California and smoked marijuana during his brief retirement from football.

In a interview last December, Williams told correspondent Mike Wallace that he had no reason to apologize to his teammates for leaving the game in his prime and in the middle of a contract.

Now, Williams tells Wallace he sees things differently.

"I found a reason to apologize. We are all different…If someone sees things differently than I do, I still have to respect them, therefore, if I hurt someone or if they felt what I did upset them, then out of respect for them, I owe them an apology," says Williams, in an interview to be broadcast on 60 Minutes Sunday, Sept. 18, at 7 p.m. ET.

Williams says his new loyalty to his team reflects a motto Dolphins coaches instill in their players: "Get out of yourself, get into the team."

Williams, who tested positive for marijuana last year, previously told Wallace that he left the team rather than face public humiliation.

He now says he's where he should be right now and that he doesn't miss the drug.

In the December 2004 interview, Wallace bet Williams that he would return to football. Now that Williams is back, will Wallace get lunch, or dinner?

"Well, I work, I have a job now, so it will have to be dinner," says Williams.
