The Swallows announced that Keizo Kawashima was examined at a hospital in Tokyo and diagnosed with a distal phalanx fracture in his left thumb. He will require about two months for a full recovery.
Kawashima suffered the injury while sliding into a base during a practice game against Surugadai University on the 8th. Junji Ogawa told reporters they were planning to call him in time for a game against either Orix on the 13th or Rakuten on the 15th.
