Musgrove left his start Wednesday in Game 2 of the National League Wild Card Series versus Atlanta due to right elbow tightness.
Musgrove's elbow began to affect his velocity in the fourth inning of Wednesday's contest, forcing him out after just 3.2 frames of one-run ball. There's no telling if he'll be available for the NLDS if San Diego advances past Atlanta. It's worth noting that the 31-year-old has already landed on the IL twice this season due to elbow-related injuries.
