BOSTON -- Royals third baseman Mike Moustakas left Monday's game with a lateral right forearm contusion after being hit by a pitch from Red Sox starter Eduardo Rodriguez in the first inning.
X-rays taken at Fenway Park were negative.
Moustakas stayed in the game after the hit by pitch and scored a run, but in the bottom of the first, the Royals replaced Moustakas as the designated hitter with Abraham Almonte.
There was some confusion about the lineup change, because the original lineup for the Royals had Moustakas at third base, and Cheslor Cuthbert as the DH.
