Tetsuya Utsumi felt discomfort in his left forearm after pitching in an exhibition game against Hiroshima on March 2. The Seibu Lions announced that Utsumi was examined at a hospital in Tokyo on March 4 and diagnosed with mild strain in his left flexor digitorum superficialis muscle. He could end up missing the start of the regular season.
This is not the first time Utsumi has had problems with his left forearm. He missed some time during the 2015 season with inflammation in the same general area.
