Ban on Shah ends on March 27, 2015.
In December last, Shah was charged with an anti-doping rule violation under the ICC Anti-Doping Code.
The sample Yasir provided in an in-competition test, which was conducted on 13 November 2015, was found to contain the presence of chlortalidone, a Prohibited Substance which appears in Section 5 of the WADA Prohibited List (in the category of Specified Substances).
In accordance with the ICC Anti-Doping Code, pending the outcome of the disciplinary process, Yasir has been provisionally suspended.
The ICC had said the matter would now be dealt with in accordance with the process set down in the Code, and until such time as the process is resolved.
