"The swelling is a little painful," Iglesias said. "It's bothering me to walk and everything, but we'll ice it down and see how it feels tomorrow morning."
Iglesias, who left Friday's game against the Mets with a right shin contusion suffered on a late slide into second base, was originally in the starting lineup for Sunday's game against the Astros. The shortstop was taking ground balls and working with double-play partner Ian Kinsler when J.D. Martinez smacked a line drive that caught him.
"I threw to first base," Iglesias said, "and I just heard, 'Watch out!' Kinsler was screaming at me, but it was too late. J.D. hit it pretty hard."
The ball hit Iglesias in the same spot as the bruise from Friday. He immediately went to the ground in pain. Iglesias was helped off the field by teammate Andrew Romine and the Tigers' athletic training staff, but he was able to put weight on the leg.
"In 25 years of professional baseball, I don't think I've ever seen a player get a line drive in the shin in batting practice," manager Brad Ausmus said. "And it happens to the one guy who's had shin problems. The odds are astronomical that would happen."
It was a scary incident for a young shortstop who missed all of last season with stress fractures in both shins. The Tigers emphasized that Friday's injury was unrelated to the fractures.
Nevertheless, Iglesias said he's talking with the Tigers' staff about wearing extra padding on at least his right shin.
"Everything that's related to my shins, I'm kind of worried about it," he said. "I missed a full year for it, but I can't control what happened today. It's just part of being out there. I'm better now than what it was in the beginning. We'll see how it feels tomorrow."
Dixon Machado replaced Iglesias in Sunday's starting lineup.
