Opener Liton Das has joined Bangladesh team in Pakistan after making a complete recovery from a bout of viral fever.
The fever had initially prevented him from traveling with the team to Sri Lanka for the tournament opener.
Bangladesh team are now in Lahore for Super Four matches of the Asia Cup.
They will take on Pakistan in their first game of the Super Four.
The Tigers lost the first game to Sri Lanka by five wickets, but then ensured qualification for the Super Four stage with the 89-run win over Afghanistan in their last group phase encounter in Lahore Sunday.
"The Asia Cup squad has a few injury concerns and the team management felt the need for an additional player going into the Super Four. We have received the Bangladesh Cricket Board medical team's clearance regarding Liton's health and have decided to send him to Pakistan," chief selector Minhajul Abedin Nannu said.
It is not sure whether the opener will straightaway play the opening game of the Super Four.
Liton was initially ruled out of the tournament and Anamul Haque Bijoy replaced him.
Bijoy however, didn't play any of the two group ties, with debutant Tanzid Hasan Tamim and Mohammad Naim opening in the match against Sri Lanka.
Tanzid had to sit out the next clash against Afghanistan as Bangladesh sent Mehedi Hasan Miraz as a makeshift opener along with Naim.
Miraz played a match-winning 112 against Afghanistan in that match to spark the debate over whether he should open against Pakistan too in the Super Four game.
