"Saif performed laboratory testing based on his symptoms, and findings have confirmed that he has typhoid bacteria in his body," the description says. The batsman is being treated and will be monitored by the BCB medical team as he recovers," BCB said in a statement on Wednesday.
The right-handed batsman failed to score in the first Test at Chattogram, forcing the team management to call up untested Naim Sheikh for the second and final Test, which begins on December 4 in Dhaka.
However, the choice of opening batsman Naim Sheikh, a regular in Bangladesh's limited-over cricket, raised some eyebrows, given that he hasn't played a red-ball match since February 2020.
Naim, who has only played six first-class games, scored two runs in his most recent long-format match and has been overlooked in red-ball cricket since his T20 debut.
"I'm not sure who will open, but Shadman Islam is the first choice, and he batted well in the national league, so he might get a chance," Mizanur said on Wednesday.
Shakib, who was in the squad for the first Test but was soon left out after failing to recover from a hamstring injury in time, is doing everything he can to be available. From November 25, the all-rounder began his preparation with his old mentor at his own MASCO - Shakib Cricket Academy, and from November 28, he began his individual practice at Sher-e-Bangladesh Stadium.
The team management is losing their sleep over the match fitness of Shakib as he did not play any competitive cricket since Bangladesh's fourth Super 12 match of the ICC T20 World Cup, due to his hamstring injury.
