The media learned on Monday that Jun Matsui suffered a fracture in his left forearm. He will likely require about five months for a full recovery.
Matsui was hit by a pitch during a Ni-gun game against Yomiuri on Sunday. He was taken to the hospital for an examination on Monday and was diagnosed with a fracture in his left ulna. He has opted not to go under the knife.
FYI: Matsui is currently leading both leagues with twelve HBPs.
