MADRID — Real Madrid's Welsh striker Gareth Bale has an injured soleus muscle in the back of his left calf, the club said Thursday, without saying how long he would be sidelined. Bale was forced off after just half an hour of Madrid's 4-0 win over Shakhtar Donetsk that opened the Spanish giant's Champions League campaign Tuesday. "The player has been diagnosed with a soleus muscle injury in his left leg. His condition will be evaluated," the club said in a short statement after medical tests Thursday. Last season Bale was sidelined for nearly three weeks with a calf problem. Should the current injury be more serious, he could miss out on sealing Wales' qualification for an international tournament for the first time since 1958 when they travel to Bosnia and Herzegovina before hosting Andorra next month. Kaka dropped Brazil has recalled Corinthians pair Gil and Renato Augusto and dropped former AC Milan and Real Madrid midfielder Kaka for next month's World Cup qualifiers against Chile and Venezuela, coach Dunga announced Thursday. Barcelona striker Neymar is suspended for both matches and was left out, although an appeal is pending. "We would like to have Neymar but that's not possible," Dunga told reporters. "We need to get behind the players we have." Dunga has subjected his 23-man squad to yet more chopping and changing. Chelsea midfielder Ramires was left out after appearing in the squad that beat Costa Rica 1-0 and the United States 4-1 earlier this month, and Atletico Madrid's Filipe Luis was recalled after missing that double-header. Kaka, who missed the Copa America in June and July, was surprisingly recalled for the Costa Rica and US games but the Orlando City midfielder has been left out again. "We used 55 players in the last qualifiers, so some that are not in this first call up, there will be a long preparation period, and they should be ready, they will have a chance," Dunga said. Renato Augusto, one of the stars of Corinthians' rise to the top of Brazil's Serie A, is included for the first time since 2011, and center half Gil returns after missing the Copa America. The South American qualifiers are in a round-robin format with all 10 teams facing each other home and away. Brazil, which has never failed to qualify for the Finals, kicks off its campaign away to Copa America champion Chile on Oct. 8 and then faces Venezuela in Fortaleza five days later.
