At least three Full Member boards have written to the ICC expressing concern over their current players asking for no objection certificates to participate in league, which was approved as a Twenty20 event meant strictly for retired players.
"Our decision not to issue a Disapproved Notice was based on the application from MCL which clearly stated that it was an event for retired players only," ICC senior operations manager Clive Hitchcock wrote in an e-mail, according to 'ESPNcricinfo'.
It is understood that the three members are Pakistan Cricket Board (PCB), Cricket South Africa (CSA), and the West Indies Cricket Board (WICB).
As per the email, Hitchcock asked the three full members to contact him immediately if they received a request from a current or non-retired player for an NOC to play in the MCL.
"Within the past week we have received notification from two Full Members that its current players have just been approached to play in the event, by requesting those players to seek NOCs from their respective Board," Hitchcock said.
