Karachi: Tainted Pakistani trio Salman Butt, Mohammad Asif and Mohammad Aamer are not ready to bow down easily and have filed a petition against the ICC imposed life bans on charges of spot-fixing.

Their lawyers confirmed that three players have appealed against the ban on Saturday.

Sources close to Asif said that his English lawyer filed the appeal along with Butt. Aamer, on the other hand, filed his appeal on Friday itself.

"Asif also filed the appeal through his lawyer on Saturday and is in London preparing for the court appearance on March 17," one source said.

Butt, Aamer and Asif were all handed minimum five-year bans by the ICC's anti-corruption tribunal for their involvement in spot-fixing on Pakistan's tour to England last year when Butt was the Test captain.

The trio was given a deadline of 21 days by the tribunal to file appeals against their bans. They also have to appear in a magisterial court in London next month to face charges of accepting bribes and trying to defraud bookmakers after an investigation by the Scotland Yard.
