Kubo was taken off the field in the 70th minute of Sunday's match against the Netherlands due to an apparent knee injury.
Analysis:
Kubo looked to be struggling at times in the second half Sunday, which would lead to his eventual exit, leaving the field with medical attention and ice on his knee. This is a major storyline to watch for the team as they advance in the tournament, as he is a major part of the attack, their star young talent. He was replaced by Koji Ogawa after starting in the center of the attacking midfield, a possible replacement if he misses further time.
