Mashrafe’s decision came just before the first match of the series against the home side in Colombo’s R. Premadasa Stadium.
“It has been a great honour for me to represent Bangladesh in T20I for more than 10 years,” Mashrafe said on his official Facebook page.
“I believe that this team is currently a balanced one and there are some promising young stars.
“This is high time for me to say good-bye to T20 format so that many youngsters can get the opportunity to showcase their talent,” he said. (Courtesy AFP)
