Perez, who fouled a ball off his right foot Saturday and had to leave the game in the fifth inning, is dealing with a bruise and doesn't have any structural damage, Chris McCosky of The Detroit News reports.
Perez's foot is in pain and swollen, but he'll see how he feels Sunday and should be considered day-to-day. He went 2-for-2 with a triple and a run scored before exiting Saturday's contest.
