The Pakistan Cricket Board has suspended international umpire Nadeem Ghauri for four years for agreeing to extend undue favors for material gain during a sting operation carried out by a Indian television channel last year. The PCB said today in a statement that Ghauri will not be considered for any appointment during the length of his ban. Ghauri has officiated in five tests, 43 one-day internationals and four Twenty20 matches. Domestic umpire Anis Siddique was banned for three years. The committee felt he initially resisted the offers during the same sting operation but finally conceded to them on their persistence.
