In the India vs Australia match on Sunday, Cummins opted to bat first after winning the toss in their World Cup opener.

Talented India opener Shubman Gill, who is down with dengue, could not recover in time and left-handed Ishan Kishan has been drafted in as his replacement.

"He (Shubman Gill) hasn't recovered in time. Ishan comes in to replace him, he will open the batting," Rohit said at the toss.
