Victor Martinez is planning to undergo a heart procedure, and will miss the rest of the season, the Tigers said on Saturday.
Brad Ausmus told reporters Martinez is planning to return next season and is not considering ending his career.
"It's common and they assured him there shouldn't be any long-term risks," Ausmus said, according to MLive's Evan Woodbery.
Martinez will head to the 60-day disabled list.
He is owed $18 million next season.
