Louis Okoye was replaced by a pinch-runner after he hit a double to left-center in the sixth inning of a game against the Orix Buffaloes at Rakuten Seimei Park on May 22. He was removed from the game as a precaution because of tightness in his right thigh.
[UPDATE 4/23 @ 9:48pm]
Okoye was examined at a hospital in Sendai today and diagnosed with an injury to his right biceps femoris that will require three to four weeks for a full recovery.
Okoye was taken off the active roster today.
