Katsuyori Shibata Injured?

There are rumblings in Japan right now concerning the health of Katsuyori Shibata as he was supposed to be the centerpiece of the first Uwai Station show that was supposed to happen yesterday at Korakuen Hall but has been postponed by Fumihiko Uei to 12/3 at Korakuen Hall and now comes word from KENTA that Shibata was his original choice to be his partner in the GHC Tag Titles tourney. KENTA said that Shibata isn’t in good health right now but never said what the exact problem is, so people are wondering what is exactly going on with Shibata right now.
