BEIJING — Promise Isaac and Victor Obinna scored to lead Nigeria over a short-handed United States team 2-1 Wednesday, earning a place in the quarterfinals of the Olympic football tournament and eliminating the Americans.

Isaac scored in the 39th minute with an easy tap-in off Chinedu Ogbuke Obasi’s centering pass and Obinna curled a right-footed shot into the top of goal in the 80th.

Sacha Kljestan converted an 88th-minute penalty for the Americans and Benny Feilhaber headed onto the post in the 90th as the United States was eliminated from Group B after the Netherlands beat Japan 1-0.

The Americans played a man short from the third minute when defender Michael Orozco was ejected for swinging his elbow into Solomon Okoronkwo’s chest while the players wrestled for the ball.
