Rival skippers Sourav Ganguly and Shane Warne were today fined 10 per cent of their match fee and reprimanded for their conduct in the Indian Premier League. While Kolkata Knight Riders skipper Ganguly was penalised for forcing the on-field umpire to refer a contentious catch to the third umpire, Rajasthan Royals` captain Warne was punished for lambasting Ganguly`s conduct in the post-match press conference. The IPL decided to suspend the on-field umpire G Pratap Kumar, for a match. ``It has been informed by Farokh Engineer, the referee in the IPL game between the two sides 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.
