KARACHI - PSL chairman Najam Sethi Thursday defended a one-year ban for fast bowler M Irfan, saying there will be zero tolerance on corruption in the sport.

Irfan, 34, is the first casualty of the spot-fixing case which surfaced during the PSL held in February-March this year. Four other players -- Sharjeel Khan, Khalid Latif, Shahzaib Hasan and Nasir Jamshed -- were also provisionally suspended in February and face lengthy bans.

Irfan, the tallest-ever international cricketer at over seven feet, was also fined one million rupees for an ‘agreed sanction’ after he confessed to the charges. Irfan's ban includes six months suspended and if he co-operates with authorities he can return to international cricket, a sentence which come former players and experts believe too lenient.

But Sethi said the rules were followed in handing down punishment to Irfan. "Irfan has been punished according to the rules in the code that are in some ways stricter than even ICC rules," he said.

Under the PCB anti-corruption code, the punishment for ‘not reporting an offer’ is from six months to a life ban. A two-member delegation of the PCB will go to England next month to question Jamshed, who allegedly played the ‘go between’ role between the players and a bookie.

Sethi said no one would be spared in fixing cases. "We shall show zero tolerance for such corrupt activities and will continue to monitor players' conduct on and off the field," said Sethi.

Pakistan has been rocked by match fixing allegations since 1995 when Shane Warne, Tim May and Mark Waugh alleged then-captain Salim Malik of offered them a bribe to underperform on Australia's tour. That formed the basis of a judicial enquiry between 1998 to 2000, resulting in life bans on Malik and Ata-ur Rehman and fines on Wasim Akram, Waqar Younis, Mushtaq Ahmed, Inzamam, Saeed Anwar and Akram Raza.
