Australian cricket chiefs have told Al Jazeera to explain their fixing allegations as the media company prepares a fresh documentary on alleged corruption in the sport. Cricket Australia (CA) and the Australian Cricketers' Association (ACA) have called out Al Jazeera for refusing to provide any evidence to support claims of match-fixing. "Enough is enough when it comes to people making unsupported accusations that have the ability to unfairly tarnish players' reputations," ACA chief executive Alistair Nicholson said in a statement on Tuesday. Al Jazeera is preparing its second documentary alleging match-fixing in cricket after an earlier program linked two un-named Australians to corruption claims. CA chief executive James Sutherland said the governing body's integrity unit had reviewed the latest Al Jazeera claims made by "a known criminal source". "From the limited information provided by Al Jazeera our team have not identified any issues of corruption relating to current or former Australian players," Sutherland said in a statement. "We have handed all material over to the ICC Anti-Corruption Unit to enable them to fully investigate and we will continue to co-operate with the ICC. "We urge Al Jazeera to provide all un-edited materials and any other evidence to the ICC Anti-Corruption Unit." Source: www.cricket.com.au * The above photo shows ACA CEO Alistair Nicholson.
