Pakistan cricket authorities have rejected Mohammad Aamer's claims they didn't educate the talented fast bowler on how to combat corruption in the sport.
Aamer was one of three Pakistani cricketers given jail for their part in spot-fixing during a Test match against England at Lord's last year.
The 19-year-old will spend six months in a young offenders' detention centre, but has sought to excuse his behaviour by saying the PCB didn't educate him on corruption failing to tell him how serious an offence it was.
The Pakistan board says Aamer had signed the players' code of conduct in March last year which clearly states that players will abide by all rules regarding betting, match fixing, corruption and any matter that could call into question the integrity of the game.
The board says Aamer also attended several courses on how to deal with corruption and warning players on the dangers of associating with strangers.
