Mohammad Amir has been fined 150% of his match fee for a disciplinary breach while playing for Sui Southern Gas Corporation against Pakistan International Airlines in a qualifying fixture of the Quaid-e-Azam Trophy in Faisalabad on Thursday.
Amir, who is under observation since being cleared to play first-class cricket in January, was booked under article 45.4 and 45.5 of the PCB's domestic Code of Conduct which relates to "intimidating a player using crude or abusive language to sledge, and making offensive remarks."
Amir, whose five-year spot-fixing ban ended in September, has been in good form for his domestic side, picking 27 wickets in three matches so far.
"Amir was penalised for violating the code of conduct," a PCB spokesman told ESPNcricinfo. "He was fined 50 and 100% for two difference offences. He was found to be sledging around and later was found exchanging crude language with PIA batsman Faisal Iqbal. The batsman has also been fined 50% of his match for engaging in exchange of harsh words in between them." Iqbal, though, denied this to ESPNcricinfo, saying that he had only been warned not fined.
In a separate incident, Mohammad Irfan, playing for Khan Research Laboratory, was fined 50% of his match fee for an altercation with the umpire during a match against State Bank of Pakistan at the Gaddafi Stadium in Lahore.
Irfan was reportedly caught changing the condition of the ball by the opponent's secret camera. State Bank of Pakistan's manager, who leveled the allegation, was also handed a fine.
