Japan's national team experienced another injury when defender Daiki Iwamasa was hurt at training.

The Kashima Antlers man suffered a deep gash in his right leg and looks certain to miss Saturday's clash with Holland in Enschede.

Blue Samurai boss Takeshi Okada has already had to replace Vissel Kobe's Yoshito Okubo and Catania striker Takayuki Morimoto who was set to make his senior international debut.

''He has cut his leg and will need stitches. He probably won't be able to play against Holland,'' Okada said of Iwamasa.

Meanwhile, Urawa Reds defender Marcus Tulio Tanaka is not fully fit and Kashima Antlers striker Shinzo Koroki sat out Tuesday's afternoon session with a sore right ankle.

After the Holland match, Japan meets African nation Ghana in Utrecht on Wednesday.
