Jasprit Bumrah has started his rehabilitation and is "pain-free" following back surgery as his India team-mate Shreyas Iyer prepares to go under the knife.

Bumrah underwent an operation in New Zealand last month and the procedure was a success.

The Board of Control for Cricket in India (BCCI) revealed paceman Bumrah began his rehabilitation at the National Cricket Academy (NCA) in Bangalore on Friday.

Bumrah has been sidelined since a home T20l series against Australia in September.

Meanwhile, Iyer will undergo surgery on his lower back next week.

The batter will remain in the surgeon's care for a fortnight before returning to the NCA to start his rehabilitation.

Iyer and Bumrah were forced to miss the ongoing Indian Premier League due to their injuries.
