Abdur Razzak, the left-arm spinner, has been added to the Bangladesh squad for the Test series in Sri Lanka. Razzak, 30, is among the most experienced players for Bangladesh in the limited-overs formats but has not been a regular in the Test side. His last Test came in August 2011, when Zimbabwe beat Bangladesh in Harare. “We received a request from the Bangladesh team management in Sri Lanka and according to their requirement Razzak has been included in the side,” Akram Khan, Bangladesh’s chief selector, said. Razzak will join the squad on Monday, in Galle where the first of two Tests is currently taking place. Meanwhile, another senior bowler, Mashrafe Mortaza said he was worried about the slow recovery from an ankle injury, though he didn’t rule out playing the ODI series that begins on March 23.
