Ikuhiro Kiyota hurt his left shoulder when he attempted a sliding catch during the fifth inning of an exhibition game against the Yomiuri Giants on February 26. He was examined at a hospital in Naha and diagnosed with a dislocated shoulder. He will report to the Ni-gun team on February 28.
[UPDATE 3/11 @ 6:25pm]
Kiyota is currently expected to be ready for the start of the regular season. He was initially told he might need to use a sling for about a month, but he went without the sling and was able to resume batting practice within two weeks.
