The Pakistan Cricket Board (PCB) issues a warning to certain former Pakistan players over participation in a cricket tournament the ICC has classified as unsanctioned. In an official statement, the PCB says it has taken “serious notice” of the involvement of some ex-players in the event. The PCB indicates that it may impose a ban on players found to have participated, linking its position to the ICC’s classification of the tournament. The statement frames the concern around compliance with official cricket regulations and the status of leagues recognized by cricket’s governing structures. The reports note that the PCB’s action is prompted by the participation itself rather than any match-specific incident. The PCB’s communication functions as a notice and potential disciplinary step, while the ICC’s designation of the league as unsanctioned provides the basis for the PCB’s concern. The details of which former players are affected are not included in the provided summaries.
