RIO DE JANEIRO: Brazil were mulling over options to replace goalkeeper Fernando Prass on Sunday after injury forced the Palmeiras goalkeeper to withdraw from the country's Olympic squad, the Brazilian Football Confederation (CBF) said. "I worked hard to fulfil my dream of playing for Brazil but unfortunately it's not going to happen this time," the uncapped Prass said on Twitter. "The exam showed a fractured elbow and I won't be able to compete in the Olympics." The CBF said they would call up another keeper to replace Prass, one of the three permitted over-age players in the under-23 squad. Brazil beat Japan 2-0 in their final warm up on Saturday, with Atletico Mineiro's Uilson playing in goal. The Rio Olympics officially open on Friday, though the men's soccer starts a day earlier, and Brazil, who are in a group with South Africa, Iraq and Denmark, will try to win the one major international title that has so far evaded them.
