Kolkata Knight Riders' skipper Sourav Ganguly was fined 10 per cent of his match fees and reprimanded for forcing the on-field umpire to refer a catch to the third umpire during his side's Indian Premier League match against Rajasthan Royals on Thursday night.Similar fate was handed out to the Rajasthan Royals skipper Shane Warne as the IPL match referee fined him 10% of his match fee for criticising Saurav Ganguly in the post-match press conference.The IPL also decided to suspend the on-field umpire in question, Pratap Kumar, for a match."It has been informed by Farokh Engineer, the Referee in the IPL game between the Kolkata Knight Riders and Rajasthan Royals in Jaipur on May 1, that he has issued an official reprimand to Sourav Ganguly, and fined him 10 per cent of his match-fee for showing dissent on the field," IPL commissioner and chairman Lalit Modi said in a statement on Friday."The Referee has also suspended Pratap Kumar for one match, on the grounds that there was no reason for him to accede to Ganguly's request to consult the TV umpire," it added.The action comes after Royals' skipper Shane Warne lambasted Ganguly for playing against the spirit of the game by not accepting fielder Graeme Smith's word on the controversial catch.Though the Royals decided against lodging a formal complaint against the former India skipper, the IPL decided to take action as "Ganguly's act of prevailing upon the on-field umpire to refer a decision to the TV umpire constitutes a Level I offence as per the ICCs Code of Conduct."The Knight Riders lost the match by 45 runs last night making it their third defeat in a row.
