The New York Knicks have acquired Tyson Chandler from the Dallas Mavericks and sent Ronny Turiaf to the Washington Wizards in a three-team trade.

The Knicks also announced Saturday they had waived Chauncey Billups and designated him as their amnesty player.

Chandler helped the Mavericks win the NBA championship last season, averaging 10.1 points and 9.4 rebounds, and will provide the interior defense the Knicks have long lacked.

The other moves were necessary to afford his contract, including using the amnesty clause so Billups' $14.2 million salary wouldn't count for salary cap or luxury tax purposes.

The Mavericks got reserve guard Andy Rautins from the Knicks in the deal, and there were other picks involved.
