The Bayern Munich star was supposed to help Neymar lead the host nation next month.
Brazil's hopes of securing a first men's soccer Olympic gold medal took a hit Monday, as Bayern Munich winger Douglas Costa has been ruled out for the competition.
Costa, who had to miss Copa America with a thigh injury, has still not recovered, according to Bayern Munich, and the 25-year-old star won't be making the trip back home.
“I greatly regret this,” Bayern Munich chairman Karl-Heinz Rummenigge said. “We all wanted Douglas to contest the Olympic Games in his home country, but the player’s health and fitness takes priority.”
Brazilian outlet Globo Esporte reports that Renato Augusto is being sought after as a replacement, pending his club, China's Beijing Guoan, releasing him. Renato Augusto, 28, would occupy Douglas Costa's place as one of Brazil's three overage players, joining Neymar and Fernando Prasse.
Globo Esporte also reports that Shakhtar Donetsk may not release attacking midfielder Fred, and that Gremio's Walace could be his replacement.
