King is no longer scheduled to start Sunday's game against the Giants and will instead make his next turn through the rotation Monday in Arizona.
San Diego will have Kyle Hart serve as its opening pitcher in a bullpen game during Sunday's series finale. The Padres didn't provide an explanation behind the late change, but the decision to scratch King adds fuel to the notion that he could be moved ahead of Monday's trade deadline. If the right-hander ends up staying put, he'll tentatively line up for a two-start week, with his second outing coming next weekend at home versus the Astros.
