A key cog in India's scheme of things at this year's World Cup, Pandya returned from a brief suspension - for his inappropriate remarks on a television show - to help secure the team's 4-1 ODI series victory in New Zealand earlier this month.
"The BCCI medical team decided to rest the all-rounder and let him undergo strength and conditioning work for his lower back at the National Cricket Academy (NCA) in Bengaluru," BCCI acting secretary Amitabh Choudhary said in a statement.
"Pandya will begin his strength work from next week."
India's Twenty20 squad now contains 14 members, while spin all-rounder Ravindra Jadeja will replace Pandya for the five one-dayers against the reigning World Cup champions.
With wrist-spinners Yuzvendra Chahal and Kuldeep Yadav having established themselves as India's frontline spinners, Pandya's injury affords Jadeja a chance to impress before India finalise the final 15 for the World Cup in England and Wales.
