After a brilliant IPL this year, Karthik finds himself in the Indian squad, for the first time in a T20 World Cup since 2010.
Jasprit Bumrah and Harshal Patel, both of who recovered from injuries, returned to the squad.
The BCCI decided to not alter their top three in the batting order, going ahead with Rohit Sharma, KL Rahul and Virat Kohli.
The veteran seamer, who was part of the T20 World Cup 2021, found a place in the reserves of Team India this year.
There was no place for Avesh Khan and Ravi Bishnoi in the squad. While Avesh had a poor Asia Cup, Bishnoi did well in the only game he played.
