United States point guard Russell Westbrook has announced he will not participate at the upcoming Olympic Games in Rio de Janeiro.

Westbrook was set to play a prominent role on the team in Brazil after winning a gold medal with USA at the London Games in 2012.

His announcement comes just days after two-time NBA MVP Stephen Curry announced that he would not participate at Rio 2016.

"After speaking with my family, I have decided to not participate in this year's Olympics," Oklahoma City Thunder's 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."

Los Angeles Clippers' Chris Paul will not be on the team after suffering a broken bone in his hand, while Washington Wizards point guard John Wall is also be unavailable after undergoing knee surgery.

With Curry, Paul, Wall and Westbrook out of the picture, Cleveland Cavaliers' Kyrie Irving, Toronto Raptors' Kyle Lowry and Portland Trail Blazers' Damian Lillard are the remaining finalists at point guard.
