Leon is out of Thursday's lineup against the Yankees, Evan Drellich of the Boston Herald reports.
Although he's notched a .312/.370/.482 line for the season, Leon's production at the plate has been rather forgettable as of late. Over the last 14 games, he's gone just 3-for-38 (.067) with 13 strikeouts. Ryan Hanigan will start at catcher for Boston when they face CC Sabathia on Thursday.
