Camby, the NBA's defensive player of the year, declined an invitation from USA Basketball managing director Jerry Colangelo to participate in the team's camp in Las Vegas this summer because of a pressing family matter.

"Marcus was honored to get invited and he really wanted to do it, but a personal family situation requires his full attention this summer," Camby's agent, Rick Kaplan, said Thursday. "He would love to have played for Team USA, but he can't make that commitment because he has to focus on his family right now.

"It was a gut-wrenching decision, but the one he had to make."

Earlier this month, Camby's wife delivered the couple's second child, a girl.

Colangelo was looking for a defensive rebounder and shot blocker to complement the offensive stars that usually fill the Americans' roster, and Camby would have fit the bill.

He averaged 11.7 rebounds last season, when he led the league with 3.3 blocks per game. The 33-year-old was named to the All-Defensive team for the first time and was voted the league's top defender.
