Mumbai, June 5 -- Shreyas Iyer, who led Punjab Kings in the recently concluded Indian Premier League, is set to replace Suryakumar Yadav as India's new T20I captain, while Tilak Varma would be his deputy, people in the know in the BCCI said.

Rohit suffered a hamstring injury in the first half of the IPL and could not field for the duration of the tournament. He batted as an Impact Player for MI.
