Japanese coach Zico has blasted Germany midfielder Bastian Schweinsteiger for his challenge on Akira Kaji.
Schweinsteiger committed the foul during the 2-2 draw in the friendly last week, and Kaji - who was stretched off - is still suffering.
Kaji should be okay for the finals, although he is a doubt for Japan's opening game with Australia and Zico is still incensed at the Bayern Munich man.
"It was an absolutely disgraceful tackle," Zico said.
"Kaji was on the receiving end of a really bad foul.
"It should have been a red card, no doubt. I feel terrible for Kaji.
"We're very worried, the fact he is still limping shows you what a bad tackle it was."
