The Indians first baseman said he thought the extent of the injury was worse than what it turned out to be: a mild high ankle sprain.
"I thought I tore a ligament or had broken an ankle or something, but obviously I didn't," LaPorta said.
Instead, LaPorta -- placed on the 15-day disabled list Saturday -- said he expects to miss two to three weeks.
He found himself in the rundown when trying to advance to third base on a grounder to shortstop. Tribe manager Manny Acta wasn't fond of LaPorta's aggressiveness in that situation, though the first baseman said he didn't regret attempting to advance.
"He knows not to," Acta said. "It's something that guys have heard in the Minor Leagues and Little League and everywhere. But sometimes it apparently kicks in, and they think they can do it."
