The Dodgers say Greinke is expected to take his next turn in the Dodgers' rotation early next week.
The right-hander is 18-3 with a 1.65 ERA this season, making him a top candidate for the NL Cy Young Award. Greinke has victories in five consecutive starts and 13 of 15 since late June.
The decision to skip a start could prevent Greinke from winning 20 games for the first time in his career. It's unclear whether Greinke would make two more starts this season with the NL West-leading Dodgers almost certainly heading to the playoffs in early October.
Los Angeles has lost four straight since Greinke's last start.
