The Royals say Perez didn't sustain a concussion Wednesday. Perez relayed through the club that he's ''fine.''
Perez was hit by a breaking ball above his left ear. The Royals catcher fell to the ground and was down for a few seconds before walking off, holding the left side of his head.
Perez was hit by reliever Johnny Barbato in the third inning. An inning earlier, Perez hit a solo home run off San Diego starter Ian Kennedy.
Last week, Perez hit the line drive that struck Cincinnati reliever Aroldis Chapman and caused facial fractures.
