Perez is not in Sunday's lineup against the Twins due to a right thumb injury, Anne Rogers of MLB.com reports.
Perez sustained the injury on a wild pitch that hit him in the right thumb in Friday's contest. He'll end up sitting for the last two games of the series against Minnesota, but with an off-day Monday, the Royals are hopeful that Perez will be back in action for Tuesday's series opener against Texas. Carter Jensen will start at catcher for Sunday's game.
