Shaw had to be carried off the field and taken to hospital for scans, which showed a lateral ligament injury.
"He will undergo an intensive rehabilitation program to hasten the recovery and be available for selection at the earliest," the BCCI said in a release.
The 18-year-old was trying to catch Max Bryant off R Ashwin at the deep mid-wicket fence when he toppled over and twisted his ankle while trying to keep the ball in play.

Shaw has been in good form and was one of the five half-centurions in India's innings in the warm-up match. He made a stroke-filled 66 off 69 balls, with 11 fours. Shaw had made a successful start to his Test career with a century and a half-century in the two Test series at home against Windies.
Shaw and KL Rahul opened in the tour match, but with the latter managing just three to extend a string of poor performances, batting coach Sanjay Bangar said one of the opening slots was up for grabs. With Shaw now unavailable, M Vijay is all set to make a comeback after being left out of the side since the second Test in England.
The first Test starts on December 6 in Adelaide.
