Kuroda-Grauer left Monday's game against the Diamondbacks due to an undisclosed injury, Martin Gallegos of MLB.com reports.
Kuroda-Grauer appeared to be in some discomfort after fouling a ball off himself earlier in the game, and he was later removed in the bottom of the sixth inning. He can be considered day-to-day until the team has an update on the nature and severity of his injury.
