The Mavericks are working on bringing Tim Thomas back to Dallas, according to a source.

Thomas started last season with Dallas but took a leave of absence to care for his critically ill wife and missed the rest of the season and playoffs.

Tim Thomas is looking to return to the NBA as a member of the Mavericks.

Thomas missed a majority of last season to take care of his ill wife.

Agent Bob Myers says he and the club are working toward a new deal that would resume the veteran's career in Dallas.

"We're hoping to get something nailed down to bring him back there," Myers said Saturday.

Thomas appeared in just 18 games for the Mavericks last season.

Dirk Nowitzki won't play for Germany at the World Championships in Turkey this summer.

Because of that, Chris Kaman will stop asking the Clippers let him play for Germany too.

If Nowitzki had played for Germany, Kaman would have wanted to join him.

The Nuggets have agreed to terms with Al Harrington on a five-year, $34 million contract.

The Mavericks were also pursuing Harrington.

Even before Al Harrington came off the market, they saw Anthony Tolliver as a viable alternative.

The Bulls, Lakers, Warriors, Jazz and Hawks are also interested in Tolliver.

The Mavericks have targeted Al Harrington in the free agency market and hope to sign him using their mid-level exception.

Dallas prefers Harrington over Shaquille O'Neal.

Tyson Chandler and Alex Ajinca have been dealt by the Bobcats to Dallas for the non-guaranteed contract of Erick Dampier, Matt Carroll and Eduardo Najera, according to a source.

Chandler believed he would be traded to the Raptors on Monday, but owner Michael Jordan backed out of the trade.

The Mavericks are looking for a big man and have shown interest in free-agent center Shaquille O'Neal, according to a source.

A source close to the center told the Dallas Morning News that O'Neal hasn't yet committed to Miami, which was speculated once LeBron James, Dwyane Wade and Chris Bosh joined forced with the Heat.

The Jazz have taken the lead in their pursuit of trading for Al Jefferson.

Sources told ESPN.com that the Jazz and Timberwolves are engaged in serious discussions on a deal that would slot Jefferson's contract into the $14 million trade exception.

Minnesota wants multiple first round picks and no additional salary in exchange for Jefferson.

The Dallas Mavericks were widely believed to be the most serious suitor for Jefferson in recent days, but the sides have been unable to agree on the terms of a deal.

The Dallas Mavericks and Minnesota Timberwolves continue to exchange proposals on an Al Jefferson trade and moved closer to a deal over the weekend, according to sources.

But the sides still don't have a done deal, sources said, despite the fact that Dallas has somewhat eased its stance on the inclusion of Erick Dampier's lucrative non-guaranteed contract in a trade for Jefferson.

The Jazz have also entered the trade talks, as they have a trade exception created by their recent Carlos Boozer sign-and-trade with Chicago is large enough to take in Jefferson's contract.
