Kershaw (back) underwent an MRI on Friday that came back clean, Alanna Rizzo of Spectrum SportsNet LA reports.
Kershaw was placed on the 10-day injured list with back stiffness Thursday after suffering the injury in the weight room Tuesday, but he appears to have avoided a major issue. The southpaw continues to receive treatment, but no timetable has been set for his return. Dustin May should serve in the starting rotation while Kershaw is sidelined.
