The Indian Premier League (IPL) on Monday rejected the request of the Pakistan Cricket Board (PCB) to advance the date of commencement of the one-year ban imposed on pacer Mohammad Asif for returning a positive dope test from September 23 to July 15, 2008.

"We have received a request from the PCB to bring forward the ban on Asif from September 23 to July 15, 2008. We cannot do so. The ban was imposed by the IPL Drug Tribunal comprising Sunil Gavaskar, Dr Ravi Bapat and Shirish Gupte," said IPL chairman Lalit Modi at a media conference here.

Modi explained that Asif had the option to go in for an appeal against the ban, imposed for one year by the IPL Tribunal for testing positive for banned drug Nandrolone in the first season of the League, but chose not to do so.
