Bangladesh coach Dav Whatmore has flown home to Australia to visit his father, who is on a life support machine after undergoing liver surgery.
Whatmore was born in Sri Lanka but raised in Australia
Whatmore missed Saturday's game against Australia and is unlikely to return before the end of their tour.
"The thoughts of the management and players are with Dav and his family at this difficult time," said Bangladesh team manager Colonel Latif Khan.
Bangladesh will be in action again on Sunday when they take on England.
Whatmore, whose 91-year-old father is also called Davenell, was born in Sri Lanka but grew up in Australia for whom he played seven Tests between 1978-79.
"It is hard to play without Dav," said Bangladesh captain Habibul Bashar.
"He has been such a great influence for us, looking after us all the time.
"But as professional cricketers you have to get on with your job, and you cannot say that anything happens on the field because he has had to leave."
