Younis Khan has been issued with a show cause notice by the Pakistan Cricket Board (PCB) for breaching clauses in his central contract.
The veteran Pakistan batsman walked out on his domestic side Khyber Pakhtunkhwa after being fined 50 per cent of his match fee for his conduct towards umpires in a Pakistan Cup match against Punjab.
Younis refused to accept his punishment and left Khyber Pakhtunkhwa in protest before apologising to PCB chairman Shaharyar Khan.
The former Pakistan captain also asked to be allowed to re-join Khyber Pakhtunkhwa, but that request was denied and the PCB has clarified its stance on the issue.
"In accepting the recommendations of Match Referee a fine of 50 per cent of his match fee has been imposed on Younis Khan," a PCB statement said.
"For breaching the following clauses of his central contract a show cause notice has been issued to Younis Khan to explain his position to the Board within 7 days:
"Clauses 2.2.1 (c), 2.2.2, 2.2.5 and 2.2.8 and Breaches No. 17 and 20 of Schedule 5 of the Central Contract.
"In light of the above pending disciplinary proceedings and due to the fact that a replacement player has already been added to the KPK Team, it has been decided, in the interest of the game, not to allow Younis to rejoin the Khyber Pakhtunkhwa team in the Pakistan Cup."
PCB chairman Shaharyar said: "Younis has been a great servant of Pakistan Cricket and a true role model for youngsters. I feel pained making this decision as we have to demonstrate that no one is bigger than the game.
"We will wait for Younis to respond before we proceed further in this matter."
