Pakistan leg spinner Yasir Shah has been provisionally suspended under the ICC's anti-doping code for testing positive for a banned substance.
A sample taken from Yasir on November 13, when Pakistan played an ODI against England in Abu Dhabi, was found to contain chlortalidone, which is on WADA's prohibited list of diuretics and masking agents.
While he is provisionally suspended, Yasir cannot play - or be involved in any capacity in - international matches, and games organised by any national cricket board or its affiliated members.
He can request for his B sample to be tested, and if that test does not confirm a positive result then the entire test will be considered negative and the suspension will be lifted.
Yasir can also request for a hearing before an anti-doping tribunal through a written application that must be received by the anti-doping manager within 14 days. Should he want a hearing, Yasir must state in his application how he responds to the charge and his explanation for the same.
Yasir, 29, has become a key member of the Pakistan team since debuting in Test cricket in October 2014. Currently ranked No. 4 in the Test bowlers rankings, he has 76 wickets from 12 Tests at 24.17. Forty-nine of those wickets have come in 2015, making him the fourth-highest Test wicket-taker overall this year till date.
Pakistan's next international assignment is a limited-overs tour of New Zealand in January.
