Indian captain Rohit Sharma is unsure about getting a settled batter at number four position ahead of the World Cup at home.
Shreyas Iyer's injury has become a concern for the Indian team as the batter got set in the said position after Rishabh Pant.
"Number four has been an issue for us for a long time," Rohit told reporters in Mumbai on Wednesday.
"For a long period of time, Shreyas has actually batted at number four and he has done well — his numbers are really good.
"Unfortunately, injuries have given him a bit of trouble. He's been out for a while and that is honestly what has happened in the last four to five years."
"A lot of these guys have got injured and you will always see a new guy coming and playing there."
Since all-rounder Yuvraj Singh's retirement in 2017, India have tried a dozen players at that spot with only Iyer and stumper-batsman Rishabh Pant batting more than 10 times.
Iyer has not played international cricket since March, while Pant's chance of making the World Cup is slim as he recovers after a horrific car crash last December.
India is also likely to miss their opening batter KL Rahul due to injury. India won the World Cup last time it hosted it, in 2011.
