"It'll probably be a couple days, I would think," Tigers manager Brad Ausmus said.
Iglesias left Sunday's game at Kansas City with what was called groin tightness. He missed Tuesday's opener against the White Sox in large part because of a forecast for wet field conditions, but he returned Wednesday and reached base twice. Ausmus said he noticed something wrong with Iglesias when he scored from second on Victor Martinez's eighth-inning single.
Iglesias told two different people he was fine and stayed in to finish the game, but he reported soreness Thursday morning. Hernan Perez started in Iglesias' place Thursday afternoon.
Though Iglesias entered Thursday ranked fourth among American League hitters with a .349 (29-for-83) average, his bigger value has been in the field, where his stellar defense has arguably put him into the American League All-Star conversation. He made a couple of highlight plays against the Royals last weekend, helping Detroit salvage a four-game series split.
