Four Pakistan cricketers will undergo dope tests before the third one-day international against England on Friday, a Pakistan team official said.
Team manager Yawar Saeed confirmed that a team of experts from the World Anti-Doping Agency (WADA) reached London and notified the Pakistan team that random dope tests would be conducted before the match, at The Oval.
Yawar said WADA did not convey which players would be picked for the tests on Wednesday but sources in the team said four senior players had been shortlisted.
"Captain, Shahid Afridi, fast bowler, Shoaib Akhtar and batsmen Mohammad Yousuf and Umar Akmal have been shortlisted for the tests," one source said.
Yawar said the dope tests are a routine matter, as the Pakistan Cricket Board is a signatory to the WADA anti-doping code which other boards had signed as well.
"Under this agreement WADA can conduct random dope tests during any competition or out of competition at any time of the year," he said.
Pakistan cricket in the past has been tainted by positive dope tests of star players like mercurial pacer Shoaib Akhtar and the currently suspended Mohammad Asif.
Both the pacers tested positive during out-of-competition tests by the PCB before the 2006 Champions Trophy and were banned. However, after appealing, the bans were lifted on technical grounds.
Asif, who has been released from the team and is serving provincial suspension by the ICC for his alleged involvement in the spot-fixing and betting scandal, also served a 12-month suspension in 2008-2009 for flunking a dope test during the Indian Premier League.
He was also detained for 19 days in 2008 at the Dubai airport for possession of small quantity of hashish but later released without any criminal charges against him.
Pakistan sports has been rocked by doping scandals in recent months and a few weeks back, the country's anti-doping agency banned 10 female and male athletes for testing positive in the National championship and during a camp for the Commonwealth Games.
