RIO DE JANEIRO, May 30 (Xinhua) -- Uncapped Internacional full-back Geferson has been drafted into Brazil's Copa America squad after an injury to Real Madrid's Marcelo, the Brazilian Football Confederation (CBF) said in a statement.
Marcelo was ruled out of the June 11-July 4 tournament in Chile after suffering a back problem during training.
Geferson, 21, is a key member of the Internacional team that has progressed to the semifinals of this year's Copa Libertadores, South America's top club competition.
The Selecao begin their Copa America campaign against Peru on June 14 before also meeting Colombia and Venezuela in the group phase.
