Russell Westbrook, James Harden say they won't play in Rio Games

— -- OKLAHOMA CITY -- Oklahoma City Thunder guard Russell Westbrook and  Houston Rockets guard James Harden became the latest stars to announce they are withdrawing their names from consideration for USA Basketball's 2016 Rio Olympics team.

"After speaking with my family, I have decided to not participate in this year's Olympics," Westbrook said in a statement. "This was not an easy decision, as representing my country at the World Championships in 2010 and the Olympics in 2012 were career highlights for me. I look forward to future opportunities as a member of USA Basketball."

Harden called his decision a "painstaking one that I did not take lightly."

"As a member of the 2012 London Olympic Gold Medal Team, and as Team Captain for the 2014 FIBA Gold Medal Team, it goes without saying that USA Basketball has provided me with some of the most meaningful personal and professional accomplishments of my life," Harden said. "I have been extremely blessed to wear the 'red, white, and blue' and to compete at the highest international level with the greatest players representing the greatest country in the world. I sincerely hope I'll earn an opportunity to represent Team USA again in the future."

Westbrook and Harden join a growing list of players who have pulled out of the original 31-player pool, including Stephen Curry (knee rest), LaMarcus Aldridge (finger), Chris Paul (hand), Anthony Davis (knee, shoulder) and John Wall (knee).

Westbrook and Harden each played for Team USA at the 2012 Olympics, with Westbrook averaging 8.5 points and Harden averaging 5.5 points in the eight games played.

USA Basketball chairman Jerry Colangelo told ESPN's Marc Stein on Monday that no players have withdrawn because of concerns related to traveling to Brazil. With rising concerns among Olympic-bound athletes because of the Zika virus, Colangelo said the reasons players have removed themselves from consideration are injury-related.

Westbrook, though, played an injury-free season. He played in 80 games, recording 18 triple-doubles and averaging 23.5 points, 10.4 assists and 7.8 rebounds. He then added another 18 games in the postseason during the Thunder's run to the Western Conference finals.

Harden played the full 82 games in the regular season, plus five in the first round of the playoffs.

Kevin Durant, Westbrook's Thunder teammate, said last week he intends to play in Rio. The Undefeated's Marc Spears reported on Friday that Sacramento Kings' center DeMarcus Cousins has been informed that he has secured a roster spot. Draymond Green and Harrison Barnes told Spears they also are available and hopeful for a spot.

USA Basketball will announce its final 12-man roster in late June after the conclusion of the NBA Finals. Training camp for the Rio games begins in mid-July.

Team USA's 12-man roster is expected to be announced in late-June. The Olympic Games in Rio de Janeiro run from Aug. 5-21.
