According to reports in Cuba, Brown arrived in the Ecuadorian city where he was expected to compete in the men’s light middleweight class only to abandon his teammates on the eve of the tournament.

Brown became junior world champion in 2012 and was part of the Cuban contingent that fought at last year’s World Championships in Belgrade.

His absence leaves Cuba with six fighters including world bronze medallist Herich Ruiz and Pan American bronze medallist Damián Arce as well as Jorge Moirán, Billy Rodríguez, Erislán Romero and Rafael Joubert.

There were no Cuban fighters in action on day two of the Elite Men’s and Women’s Championships.

The Brazilian team enjoyed four victories yesterday but were only able to secure one today courtesy of Jhonatan Conceição.

Conceição overcame Adrian Roache to advance to the next round of the men’s light middleweight division.

There was disappointment for fellow Brazilians Caroline Almeida, Tatiana Chagas and Jucielen Romeu who all suffered defeats.

Puerto Rican Melody Vargas got the better of Almeida in the women’s flyweight category, while Ecuadorian Helen Sanchez saw off Chagas in the women’s bantamweight division.

Pan American silver medallist Romeu lost by split decision to Puerto Rican Ashleyann Motta in the women’s featherweight class.

Canada enjoyed plenty of success with Scarlett Delgado beating Estefani Almanzar de Leon of Dominican Republic in the women’s bantamweight division, Dylan Martin seeing off Arvin Solognier of Aruba in the men’s middleweight category, Tammara Thibeault overcoming Naomi Graham of the United States in the women’s middleweight class and Priyanka Dhillon beating Belisa Lopez in their women’s minimumweight bout.

Competition is due to continue tomorrow.
