Kashima Antlers coach Oswaldo Oliveira has confirmed that two of his stars are in doubt for tonight's Asian Champions League clash with Suwon Bluewings.

Brazilian forward Marquinhos (groin) and defender Daiki Iwasama (leg) may both miss the important encounter in Kashima.

"I'll wait until tomorrow to decide on whether to play them," Oliveira said yesterday.

"Even if we are without them, we have the players who can replace them. I'm not concerned at all."
