Another boxing loss for the United States

ATHENS, Greece, Aug. 23 (UPI) -- Super-heavyweight Jason Estrada became the latest American Olympic boxing casualty Monday when he fell in the quarterfinals.

Estrada was eliminated by Cuban Michel Lopez Nunez.

Estrada, who beat Nunez to win gold at the 2003 Pan American Games, was outpointed from the beginning en route to a 21-7 loss.

That setback left just two Americans in the boxing competition -- middleweight Andre Dirrell and light heavyweight Andre Ward.
