Mohammad Amir is set to quickly start the process of trying to rescue his cricket career after returning to Pakistan following the completion of his sentence for spot-fixing. He understands that one of his early aims is to pursue his appeal before the Court of Arbitration for Sports (CAS) against the five-year ban handed out by the ICC. Amir returned to Pakistan on Saturday after being released from a young offenders' institute in Dorset after serving half of a six-month sentence handed down in November. The CAS, based in Switzerland, registered Amir's appeal in March 2011 - filed at the same time as those of Mohammad Asif and Salman Butt - after an ICC tribunal had banned the trio from playing any level of cricket.
