KARACHI (AFP) - The Court of Arbitration for Sports (CAS) on Wednesday rejected an appeal from Pakistan's former cricket captain Salman Butt against a 10-year ban imposed for spot-fixing, Butt's lawyer told AFP.

"The appeal has been rejected," Yasin Patel told AFP from London, refusing to elaborate further.

Butt is expected to speak to the press shortly in the Pakistani city of Lahore.

Butt and two of his fast bowlers, Mohammad Asif and Mohammad Amir, were all banned by the International Cricket Council (ICC) in 2011 after being found guilty of deliberately contriving no-balls in return for money in the Lord's Test in England in 2010.

The now-defunct British newspaper the News of the World exposed the players in a sting operation involving their agent Mazhar Majeed, who struck a deal for £150,000 (S$283,500) with an undercover reporter.

Butt, now 28, was banned for 10 years with the possibility of five suspended and all three were jailed in England in November 2011.

Amir, banned for five years, pleaded guilty in court and decided not to appeal against the ICC ban, while a decision on Asif's appeal is still pending.

The appeals of Butt and Asif were heard by a three-member CAS panel led by lawyer Graham Mew and accompanied by Romano Subiotto and Robert Reid.
