Japanese hammer thrower Koji Murofushi will sit out the remainder of the season, citing health problems, sources close to the athlete said Thursday. Murofushi, the Athens Olympic gold medalist, will skip the Seiko Super meet Sept. 19 in Yokohama and has already expressed his intentions to the Japan Olympic Committee to withdraw from the East Asian meet in Macao in October, the sources said. After experiencing problems with his left side in the spring, Murofushi missed the world championships in August in Helsinki and the Asian championships last week in South Korea.
