Coach Rick Carlisle confirmed to media members Sunday afternoon that Deron Williams is "done for the year."

The point guard had tried to play in game 4 on Saturday, but had to exit after 89 seconds when his sports hernia/left abdominal strain became too painful.

Williams said he's been told that rest - perhaps a month or more - is the only thing that will cure the problem. And even that might not be enough to avoid surgery to fix it.

Without Williams, the Mavericks have gone with a committee at point guard, using Raymond Felton, J.J. Barea and Devin Harris.

"He had a very strong year," Carlisle said of Williams. "He played great basketball for us. The only thing that derailed him were some health issues."

In his 11th NBA season, Williams played 65 games, virtually the same as he has the past two seasons. He averaged 14.1 points and 5.8 assists, again, very similar to his last two seasons.

He can become a free agent on July 1 if he opts out of the second season of his two-year, $11-million contract.
