McCullers has been scratched with a blister for Tuesday's start against the Angels, Brian McTaggart of MLB.com reports.
It doesn't appear that this blister will force a DL stint or even another missed start at this point. Scott Feldman will start Tuesday in his place. We'll watch for updates on McCullers's next appearance, but if the rest of Houston's starters pitch in turn, McCullers's next start will fall July 4 against Seattle.
