Shreyas Iyer's back injury isn't apparently very serious but concerns remain about his availability for India's final Super 4 game against Bangladesh on Friday as the national selection committee is set to name the squad for the three-match series against Australia sometime during the week. Iyer, who has come back after a long lay-off and a back surgery to cure his stress fracture, played against Pakistan and Nepal in the group league stage before pulling out of the match against the arch-rivals at the eleventh hour, complaining back spasms. A clearer picture will emerge on Thursday during the optional training ahead of the Bangladesh game.
