Louis (Rui) Okoye hurt his right leg while chasing down a drive into right-center in the 6th inning of Friday's game against South Korea. He was replaced by a pinch-hitter in the bottom of the inning. It was later announced that Okoye suffered a cut on his right thigh. Four stitches were required to close the wound.
The latest injury could prove costly for Japan. The cut is not expected to keep Okoye out of the line-up over the weekend, but it could affect his mobility. To make matters worse, the Japan is already down one outfielder -- Hiroshi Toyoda was diagnosed with a fissure fracture in his left knee after an HBP during the Australia game on August 30.
