Bangladesh had to use two concussion substitutes after Liton Das and Nayeem Hasan were hit on the helmet by Mohammed Shami. The visitors' choice of replacements though put their planning for this Test series in bad light.

While there was one bowler for bowler swap with Taijul Islam taking Nayeem's place, Mehidy Hasan, a specialist spinner, took over from Liton Das, a wicketkeeper batsman, meaning he cannot bowl for the entire duration of the game. As per the ICC Playing Conditions, a concussion substitute has to be a like-for-like replacement and perform the same role as that of the concussed player. Both Liton and Nayeem have gone to the hospital for scans.

It is unclear why the BCB didn't call in replacements considering both Saif Hassan and Mosaddek Hossain were ruled out long before day one of the Eden Gardens Test.

Saif's injury was confirmed on November 20, two days before the game, and although there are 30-minute flights between Dhaka and Kolkata, no one was was flown in. Mosaddek meanwhile, had left the Test squad on November 11, even before the first Test, to be with his ailing family member, but the BCB didn't name a replacement.
