Colombian referee Hector Parra (37) failed the fitness test for the U-20 World Cup 2011 that will start this week in Colombia. He was initially selected as a reserve referee and FIFA decided to replace him with another referee from the host country, Jose Buitrago (41, photo), who participated in the FIFA U-20 World Cup 2007 in Canada and the FIFA U-17 World Cup 2007 in Korea.
