Argentina's women's basketball team had to forfeit its game against Colombia at the Pan American Games on Wednesday for wearing the wrong uniform color and can no longer advance to the medal rounds.

The Argentines were supposed to wear white jerseys as the away team but came onto the court in Lima in blue, the same color as Colombia. They had 15 minutes to correct the mistake but couldn't get the right shirts in time, leading to Colombia being awarded a walkover 20-0 victory.

The blunder prompted the resignation of women's basketball development director Karina Rodriguez and Argentina team leader Hernan Amaya.

"It's one of the saddest moments of my career,'' Amaya said. "I take full responsibility for what happened.''

Argentina, correctly wearing their white jerseys on Thursday, defeated the Virgin Islands 73-59 and will play in the fifth-place game.
