The secretary of the Karachi City Cricket Association (KCCA) Professor Ejaz Farooqi said notices were given to Fawad Alam, Khalid Latif and Sohail Khan who have represented Pakistan.
"The three were given show cause notices on the report of the manager, Visal Ansri and coach, Tauseef Ahmed," Farooqi said.
The three players have been asked to submit their replies within three days after which the KCCA will form a disciplinary committee to look into their cases.
"As far as these three are concerned their issues are more serious. Fawad took off his pads and stormed out of the dug out and went into the dressing room during the match against Bahawalpur when the captain decided to send another player ahead of him in the batting order," Farooqi explained.

"Sohail misbehaved with the coach after the last game and Khalid didn't cooperate with the team officials after he was not appointed vice-captain for the tournament," he added.
Karachi Dolphins which had reached the finals of the first two editions of the super eight cup were knocked out in the group matches leading to the resignation of chief selector and former Pakistan captain Rashid Latif.
But Farooqi said he had not accepted the resignation of Latif and had asked him to continue working as chief selector.
