China's head coach Bora Milutinovic is considering of replacement for two injured defenders in the match against Brazil on Saturday.
Fan Zhiyi and Sun Jihai, the top two defenders of the World Cup debutantes China, will probably miss the match due to injuries.
"The two players are receiving treatment," said team doctor Li Yuhua on Thursday.
Sun Jihai sustained a right ankle injury 25 minutes into the match against Costa Rica and had to be substituted. Fan Zhiyi, whoplays for Scotland team Dundee, was also taken off in the second half.
Sun and Fan didn't take part in training on Thursday.
"They will not be able to play," said China coach Bora Milutinovic, "It's very difficult for them to recover in 48 hours."
If Sun and Fan can not play on Saturday, Milutinovic will probably send on Zhang Enhua and Qi Hong.
