USA Basketball's training camp in Las Vegas will end Saturday night with an intrasquad game at the Thomas & Mack Center.

The roster will be trimmed sometime after that before Team USA reconvenes in New York next month for the World Championships to be held in Turkey Aug. 28-Sept. 12.

"We have time on our side in terms of selection," USA Basketball chairman Jerry Colangelo said Friday.

"We're still talking about 14 or 15 going to New York. Names could change a little bit based on today and based on what we see tomorrow night, because we're giving everyone the benefit of the doubt. If there are any close calls we may even take an extra guy. We'll see."

Amar'e Stoudemire appreciates the Knicks' position in removing him from this summer's national team.

"I understand the New York Knicks' concern, also wanting to make sure I'm totally healthy for next season," Stoudemire said. "I'm looking forward to having a big year with the Knicks organization, so I understand both sides."

If a team cannot obtain insurance on a player, that team can stop the player from participating in events during the off-season.

"He had to pull out because he couldn't get insurance on his knees. So, he's not able to play," Mike D'Antoni said. "I don't know if his [future USA Basketball] status has changed or not. I have no idea. I hate it for him, but it's business."

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 Knicks found out on Friday that Amar'e Stoudemire's surgically repaired knee would not be covered by insurance and notified Stoudemire on Monday that the team will not permit him to play on the national team this summer.

"There?s too big a risk out there," Donnie Walsh said.

Stoudemire had microfracture surgery on his left knee in 2005.  He was signed to a maximum-salary contract by New York earlier this month.

Wizards center JaVale McGee has been added to Team USA's training camp roster.

A total of 22 players will begin practicing on Tuesday in preparation for the 2010 World Championships in Turkey.

McGee practiced with Team USA in a minicamp last summer and received the invite after impressing with Washington during the Las Vegas Summer League.

He will be the fourth center on the roster, behind Brook Lopez, Tyson Chandler and Robin Lopez.

Knicks forward Amar'e Stoudemire's availability for the World Championships was thrown into doubt on Monday.

Sources told ESPN.com's Chris Sheridan that Stoudemire's contract with New York may not be insured to allow him to play in a FIBA competition.

The news is a blow to Team USA and to the Knicks, who signed Stoudemire to a five-year, $99.8 million contract earlier this month.

Team USA is expected to hold it's first practice on Tuesday and more is expected to surface regarding Stoudemire.
