Sarfraz immediately reported the approach to Pakistan's management, who then passed it on to the ICC's Anti-Corruption unit (ACU). The ACU will now take over the investigation.
"A player was approached," PCB chairman Najam Sethi tweeted. "As per rules he immediately reported to PCB who informed ICC. Matters are jointly in hand. No further comment."
Earlier this year, in February, a few Pakistan players were the target of corrupt approaches during the second season of the Pakistan Super League (PSL), which was also held in the UAE. From that case, a number of players were punished by the PCB for failing to report the approaches and two - Sharjeel Khan and Khalid Latif - have been found guilty and banned for more serious breaches of the PCB's anti-corruption code.
