Japan scrumhalf Fumiaki Tanaka has left the team due to a dislocated right shoulder and is unlikely to play against Scotland this month, the Japan Rugby Football Association announced Monday.
Tanaka, who also plays for Panasonic Wild Knights and the Super Rugby champion Highlanders, was injured in Saturday's test against Canada in Vancouver. And he is considered unlikely for either of the two tests against Scotland.
The Brave Blossoms will also be without flanker Yoshiya Hosoda, who has received a two-week suspension from World Rugby for dangerous play in Japan's 26-22 win over Canada.
Scotland and Japan will square off on Saturday at Toyota Stadium in Aichi Prefecture, and will clash again seven days later at Tokyo's Ajinomoto Stadium.
