Shoaib Akhtar and Danish Kaneria will appear before a Pakistan Cricket Board (PCB) disciplinary committee on Tuesday to respond to charges of violating the players' code of conduct.
The duo were charged with criticising PCB policies following the board's announcement of the new central contracts in January.
Paceman Akhtar was dropped from the list of contracts while leg-spinner Kaneria was demoted.
If found guilty, they face fines of between one and five million rupees (between $17,000 and $82,000) or bans ranging from three to six matches.
"I can confirm we have called both players for a hearing on Tuesday to hear their viewpoint on the charges," disciplinary committee chairman Muneer Hafeez told Reuters on Monday.
Akhtar was last year banned for 13 matches and fined 3.4 million rupees for hitting team mate Mohammad Asif before the Twenty20 World Cup in South Africa.
