In a letter to Zimbabwe Cricket chairman, Wilson Manase, the 30-year-old spinner said Campbell has a "personal agenda against him which influenced his non-selection (in the playing XI) at the recent World Cup".
According to a report in 'ESPNcricinfo.Com', Utseya alleged that Campbell "appointed white coaches and administrators during his 2010-2012 stint as chairman of the cricket committee in order to take control of cricket".
"(Campbell) had a conflict of interest in setting up Dominus Sport, the company that ran ZC's marketing affairs during his time as cricket committee chairman, and his actions had an impact on ZC's funds," Utseya said in the letter.
Headlined 'Racism and Victimisation', the letter begins, "Through you Mr. Chairman I wish to share my frustrations as I believe I am a victim of racism and have come to a point where I feel I have been quiet for too long whilst a lot has been happening."
Utseya was banned from bowling by the ICC after testing in September 2014. In December, his offbreak was found to be illegal but his other deliveries were deemed legal, and so he was cleared to bowl again so long as he did not utilise his stock ball.
