Chicago Bulls forward Luol Deng is one of three NBA players who have agreed to play on Britain's Olympic team.
British basketball says Deng, Detroit Pistons guard Ben Gordon and Charlotte Bobcats center Byron Mullens have "confirmed their availability and commitment" to play at the Olympics.
They are part of a 21-man preliminary squad.
While Deng has played on the British team since 2007, Gordon and Mullens are available for the first time.
The international basketball federation allowed Britain's men's and women's teams to compete at the 2012 London Olympics without qualifying.
