Phillies' Andrew Painter: Undergoing tests for sore elbow

Painter will undergo testing due to renewed right elbow discomfort, Todd Zolecki of MLB.com reports.

Painter had to be scratched from a throwing session earlier this week due to elbow stiffness, and he reported further discomfort after a bullpen session Wednesday. The young hurler had been working his way back from a partially torn UCL, and with this setback the worry now has to be that Tommy John surgery could be looming.
