Takeya Nakamura (left hip) was taken off the active roster on June 16. He is eligible to return on June 26, but the Seibu Lions want him to return at full strength and realize he could miss a considerable amount of time. They could wait to bring him back until after the All-Star break.
[UPDATE 6/23 @ 10:36pm]
An examination at a hospital on June 21 did not reveal any bone injuries.
