New York: The New York Knicks have acquired center Tyson Chandler from the Dallas Mavericks as part of a three-team trade, the Knicks said on Saturday.

"Signing a player of Tyson's calibre, with championship experience, to this roster, is an opportunity we could not pass up," Knicks interim general manager Glen Grunwald said in a statement.

Chandler, 29, averaged 10.1 points and 9.4 rebounds in 74 regular-season starts for the NBA champion Mavericks last season. He has spent 10 years in the NBA with Chicago, New Orleans, Charlotte and Dallas.

"Tyson will be the anchor to our defence," Knicks coach Mike D'Antoni said. "The trio of Amar'e Stoudemire, Carmelo Anthony and Tyson makes one of the most formidable frontlines in the entire league."

The Knicks sent forward Ronny Turiaf, cash considerations and a 2013 second-round draft choice to the Washington Wizards and guard Andy Rautins to Dallas as part of the deal.

Roy retires

Dallas traded a 2012 second-round draft choice to Washington and the draft rights to forwards Ahmad Nivins and Giorgos Printezis to New York.

The Mavericks also gained a conditional future second-round draft choice from Washington. Portland Trail Blazers guard Brandon Roy is retiring because of ongoing knee problems, the three-time All-Star said.

"After consulting with my doctors, I will seek a determination that I've suffered a career ending injury," Roy, 27, said in a statement.

"My family and health are most important to me and in the end this decision was about them and my quality of life, " said the 2007 NBA rookie of the year.

The sixth overall pick in the 2006 draft, Roy experienced knee problems throughout his career, undergoing surgery on both knees in January and missing long stretches of last season.

He finished the season with a career-low average of 12.2 points in 47 games, far below his career average of 19 points, 4.7 assists and 4.3 rebounds.
