Diver Yu Terauchi will not compete at the upcoming World Championships in Barcelona, Spain, the Japan Swimming Federation said Tuesday.

Yu, the younger brother of diver Ken Terauchi, won the men's diving championships at the national indoor swimming meet in April but injured his right shoulder in the process. He has not fully recovered from the injury and was deemed unfit to compete at the world meet which gets under way from July 12-27.

Ken Terauchi will be the only diver representing Japan in the men's competition.
