Massey (head) is out of the lineup for Wednesday's game against the Blue Jays.
Massey will need at least one day off following his removal from Tuesday's 5-3 win after falling and hitting his head while making a throw to first base. Per MLB.com, Massey showed improvement after exiting the game, and the Royals haven't indicated that he's exhibiting any symptoms of a concussion. Tyler Tolbert will fill in for Massey at second base in the middle contest of the three-game series.
