After Hiroki Kokubo returned home yesterday and crawled into bed, he felt intense pain in his left side. He was examined at a hospital today and was diagnosed with a fracture.
Said Kokubo, "It's broken. Yesterday, when I got into bed, I heard a cracking sound and knew it. I'm hoping to make it back in early September."
UPDATE @ 8:15pm - It's a fracture in his left 9th rib.
