Dollander was removed from Thursday's start against the Pirates due to an apparent injury, Colin Beazley of the Pittsburgh Post-Gazette reports.
Dollander surrendered three runs on four hits during the opening frame and exited with training staff after giving up a double and a walk to begin the second inning. The specifics of the situation aren't clear, and the right-hander should be considered day-to-day as he continues to be evaluated.
