Johnson is out of the lineup for Monday's game against the Cardinals.
Johnson started in right field in both of the Padres' final two games of the weekend series against the Mets with New York sending a pair of southpaws to the mound, but he'll be back on the bench Monday with right-hander Kyle Gibson on the hill for St. Louis. He remains confined to the short side of a strict platoon in right field with the lefty-hitting David Peralta while Fernando Tatis (adductor) remains on the injured list.
