Rupp is not in the lineup Tuesday against the Rockies, Ryan Lawrence of PhillyVoice.com reports.
Rupp will take a seat for the second time in three games as Andrew Knapp draws the start behind the dish. The 28-year-old backstop is slashing .248/.330/.446 with four homers and 13 RBI through 101 at-bats, so he could be a useful fantasy option in deeper leagues.
