Rupp is not in the lineup for Monday's game against the Blue Jays, Matt Gelb of the Philly Inquirer reports.
Rupp will take the day off to rest while Carlos Ruiz gets the start behind the plate. The 27-year-old is just 1-for-15 over his last four games, but is still hitting a solid .262 with four home runs and 12 RBI on the season.
