Last week was a mistake, but this time it’s official.

African-American boxer Errol Spence has been eliminated from any chance of winning a medal after losing Aug. 7 to Russian boxer Andrey Zamkovoy, 16-11, in the quarterfinals of the men’s welterweight division of the 2012 Summer Olympic Games in London.

Spence thought he was eliminated for a few hours last week when ringside judges ruled that he had lost his Aug. 3 match to Indian boxer Krishan Vikas. But Team USA challenged the decision, prompting the International Boxing Association’s (AIBA) competition jury to review the fight. After further review, the jury noticed that several fouls had been committed by Vikas and overturned the decision, giving Spence the victory.

The three-time national champion from Desoto, Texas told reporters that he planned on taking advantage of the second opportunity to advance on to the quarterfinals. Instead, he started out slow against Zamkovoy, losing the first round by a point. He fought better in the second round, pushing Zamkovoy up against the ropes as he pounded away, knocking the Russian’s headgear loose. But Zamkovoy responded by punching back, standing toe-to-toe with Spence down the stretch of the match.

The U.S. will now leave this summer’s Games with no boxing medals as Spence was the final U.S. boxer in contention.
