Evans was suspended by Boston as manager on 4 July 2002 after a much-publicised Football Association (The FA) investigation into "contract irregularities". He later resigned as manager of the club in September 2002, after still being suspended by the club. He was found guilty by The FA in December 2002 of impeding an FA inquiry into contract irregularities. Evans was also suspended from the game for 20 months in January 2003 for involvement of the affairs of Boston, in which players' contracts lodged with the FA contained false salary details. Evans was further accused of impeding the inquiry and fined £8,000. Evans lodged an appeal against charges in May 2003, but The FA rejected his appeal later that month and the punishment stood. Evans later pleaded guilty in court to conspiring to cheat the public revenue, and was given a 12-month prison sentence, suspended for two years.
