DUBAI: Pakistan leg-spinner Yasir Shah has been banned for three months after failing a doping test last year, sources in the Pakistan Cricket Board said.

The 29-year-old tested in November last year and was provisionally suspended by the International Cricket Council a month later after his urine sample was found to contain chlortalidone, a diuretics and masking agent on the World Anti-Doping Agency probihited list.

Shah has emerged as a match-winner for Pakistan in Tests after ace spinner Saeed Ajmal lost form having remodelled his illegal bowling action.
