"We are very excited that Serge will continue as a core member of the Thunder for years to come," Presti said.

At the Olympics, the Democratic Republic of Congo native played for Spain and went against three of his teammates in the gold medal final against the United States -- Kevin Durant, Russell Westbrook and James Harden.

Ibaka, who was selected 24th in the 2008 NBA Draft, averaged 8.0 points, 4.4. rebounds and 1.25 blocks in 15.1 minutes a game at the Olympics.

Ibaka is currently hosting a youth basketball camp in the Democratic Republic of Congo and will take part in a Basketball Without Borders program in Johannesburg, South Africa, before returning to Oklahoma City.
