While a handful of athletes from other sports have pulled out of the Olympics due to health fears over the Zika virus in Brazil, no NBA player has yet to cite the mosquito-borne virus for their decision.
Zika can cause crippling birth defects and, in adults, has been linked to the neurological disorder Guillain-Barre.
Among the other American NBA players who have already opted out of consideration are two-time reigning NBA MVP Stephen Curry, Russell Westbrook, James Harden, Chris Paul, Anthony Davis, Blake Griffin, John Wall and LaMarcus Aldridge.
The US men's team will still likely be the deepest and most talented squad in Rio, but they may not be quite as dominant.
Carmelo Anthony, DeAndre Jordan, Jimmy Butler, Klay Thompson and Toronto Raptors teammates Kyle Lowry and DeMar DeRozan have committed to representing the United States in Rio and others are expected to compete at the team camp.
USA Basketball will officially announce its 12-man roster for Rio next week.
