The Mavericks don't expect forward Tim Thomas to return this season.

Thomas has missed most of the last two months as he cares for his wife, Tricia, who has been suffering from a serious health issue.

"I had to give up doing something I love to take care of someone I love," he said.

Thomas wants to keep the nature of his wife's illness private.

"Tim has the organization's full support and understanding," coach Rick Carlisle said. "The door's open for him to return if that becomes a viable option for him and his family. But we completely understand the urgency of his situation. Our thoughts and prayers will continue to be with him and his family."
