The US Olympic Committee is not happy about its men's boxing team not winning a single medal at the London Olympics, and says changes to the sport's national governing body are coming as a result.

American boxing has a proud history at the Olympics and this was the first Games where the men have failed to bring home a medal.

US men's Olympic boxers have won a record 108 medals, with winners including Floyd Patterson, Cassius Clay, Joe Frazier, George Foreman, Ray Leonard, Roy Jones, Evander Holyfield, Oscar De La Hoya and Floyd Mayweather.

But since David Reid took gold at Atlanta in 1996, only one American man - Andre Ward, in 2004 - has taken the Olympic title.

"We have a pretty strong and rich history in boxing," said USOC CEO Scott Blackmun.

"I think in (Los Angeles in 1984), we won gold in every weight class except one. This is the first time, I think, in history that we haven't had any men on the podium. We have to fix that. We have to change that."

USOC CEO Scott Blackmun offered no specifics Saturday on what may happen, though it is clear far more is expected from US fighters going forward.

"We're going to sit down and take a hard look at why we are where we are, and make some changes," Blackmun said. "I don't want to say anything beyond that."

Two American women won boxing medals in London. Claressa Shields won a gold medal in the middleweight class and flyweight Marlen Esparza claimed a bronze.
