Blackmon is absent from the lineup for the first game of Tuesday's doubleheader versus the Dodgers.
Kris Bryant will take a turn in the DH role as Sean Bouchard patrols right field. Blackmon had a productive couple of weeks in August, but the 37-year-old is batting .232/.325/.348 with zero home runs in 19 games (80 plate appearances) since the calendar flipped to September.
