Nigeria shocked the United States 90-87 in a pre-Olympic basketball friendly in Las Vegas, Nevada, on Saturday.

Nigeria, with six NBA players and former NBA head coach Mike Brown at the helm, became the first African nation to beat the USA, who were playing the first of a five of tune-up games before the Tokyo Olympics.

The United States were without three players still active in the NBA Finals.

Brooklyn Nets star Kevin Durant led the Americans with 17 points.

Nigeria, which had 12 NBA players in its 49-man training camp in California and seven in uniform on Saturday, was led by Gabe Vincent with 21 points.

“I’m kind of glad it happened,” USA head coach Gregg Popovich said, noting that the Nigerians have had the luxury of training together since late June while the US side had assembled just four days earlier.

Popovich said the defeat should be seen as a learning experience and not “the end of the world.”

Nigeria’s win came nine years after the United States crushed the Nigerians 156-73 at the London Olympics.
