The Padres placed Darvish (back) on the 10-day injured list Sunday, Bob Scanlan of Bally Sports San Diego reports.
As anticipated, Darvish will be forced to miss at least one more turn through the rotation after a bout with lower-back tightness cut his most recent outing Thursday against the Diamondbacks short. The banged-up San Diego pitching staff has few reinforcements on hand to replace Darvish, but Reiss Knehr -- who was recalled from Triple-A El Paso in a corresponding move -- could be one candidate to pick up a spot start while the reigning National League Cy Young Award runner-up is sidelined.
