The Cardinals announced that Arenado was removed in the top of the eighth inning of Wednesday's game against the Marlins due to a right elbow contusion.
Initial X-rays on Arenado's elbow appear to have returned negative, but he'll undergo further medical evaluation as the Cardinals look to ascertain that he's not dealing with anything more than a bruise. Before he was lifted from the game for a pitch runner after being hit in the elbow by a 94 mile-per-hour sinker during his fourth plate appearance of the day, Arenado went 2-for-3 with his first stolen base of the season and a run scored.
