Curtiss was removed from Game 2 of Tuesday's doubleheader against the Cubs with right elbow discomfort, Adam McCalvy of MLB.com reports.
Curtiss recorded two outs and allowed a run on two hits while recording a strikeout before leaving the field with an athletic trainer. The right-hander attempted to remain in the contest but was ultimately pulled by manager Craig Counsell. He should be considered day-to-day until the specifics of the injury are known.
