Dr Shyamasish Banerjee attending on Akhtar said, ''Akhtar is suffering from chest infection and severe dehydration. He has been administered intravenous fluid.'' But Dr Banerjee hoped Akhtar might be released on Wednesday.
Meanwhile, Misbah-ul-Haq, who is also running a high temperature was being attended by Dr Joy Basu at the team hotel.
Misbah went for a blood test for the second time, while another speedster Mohammed Sami also underwent blood test.
However, Pakistan team sources said the injury to skipper Shoaib Malik was not so serious. ''It's a Grade-1 sprain and he should be fit for the Test,'' sources added.
The Pakistan team arrived here this morning and is scheduled to begin practice from tomorrow.
These three players hold the key to Pakistan line-up. While Akhtar chipped in seven wickets in the first Test in New Delhi, Sami was spectacular in his line and length.
Misbah had been in fine nick for long and was the top-scorer in the first innings of the first Test.
