Kyohei Kamezawa may have hurt his left knee while try to advance to second on a throwing error during the fourth inning of a game against the Yomiuri Giants at Nagoya Dome on July 18. He was replaced by a pinch-hitter in the fifth inning and taken to a hospital in Aichi for tests. It is uncertain how much time he will miss.
Kamezawa was taken off the active roster on July 19.
