The Diamondbacks placed starting pitcher Shelby Miller on the 10-day disabled list Monday with right elbow inflammation, the team announced.
Miller was forced from Sunday's start with what had originally been described as forearm tightness.
The new diagnosis seems like an encouraging sign he won't miss extended time.
After an abysmal first season in Arizona, one which occurred after the Diamondbacks sent Dansby Swanson to the Braves, Miller has shown signs of life this season. The 26-year-old righty is 2-2 with a 4.09 ERA through four starts.
Archie Bradley, who has been one of the team's best relievers this season, is a likely candidate to replace Miller in the rotation.
