Mohammad Irfan has been banned for a year by the Pakistan Cricket Board (PCB) after pleading guilty to two breaches of its anti-corruption code.
The Pakistan paceman was provisionally suspended this month after being questioned by the PCB's anti-corruption unit in February as part of an investigation related to the Pakistan Super League (PSL).
Irfan, who has made 84 appearances for his country in all formats, was alleged to have failed to disclose full details of approaches and invitations received by him to engage in corrupt conduct.
The giant 34-year-old's international career could now be over after he admitted the charges levelled against him and was banned for 12 months, half of which will be suspended if no further breaches of the PCB code are made in the next year and no other previous offences come to light.
PCB chairman Shaharyar Khan and PSL counterpart Najam Sethi said: "It is important for all players to take note and be reminded of their responsibilities and obligations under the PCB anti-corruption code and that no form of corrupt activity shall ever be tolerated by PCB."
Irfan also had his central contract cancelled and must pay the PCB one million rupees ($154,000), as well as "provide substantial assistance to the PCB vigilance and security".
He may also be required to deliver lectures on anti-corruption as part of the PCB's anti-corruption education programs.
Pakistan duo Sharjeel Khan and Khalid Latif were also provisionally suspended for alleged breaches of the PCB anti-corruption code last month along with former international Shahzaib Hasan.
