There is this article on cricinfo which talks about the lack of black cricketers for england. Mentions racism from the establishment, a glass ceiling as one of the reasons.

Piper cuts to the chase. "Racism goes on. We have to be aware of it. One reason black players aren't progressing as fast as Asians is that we haven't learned how to not be like these people, haven't found a way to act in front of them."
Two wounds left deep scars. On the eve of the 1995 series against West Indies DeFreitas finally "responded" to racial provocation, when Wisden Cricket Monthly published an article headed "Is it in the blood?". DeFreitas, Malcolm et al, the writer Robert Henderson opined, were not "unequivocal Englishmen". (In 1990, shortly after bowling England to their first Test win in the Caribbean in 16 years, Small and Malcolm had been similarly typecast by Norman Tebbit.) DeFreitas and Malcolm, then Derbyshire confreres, sued and settled out of court. Malcolm's justly gotten gains made his cricket school in Sheffield a reality. "He suggested [we] were interlopers," recollects DeFreitas, perpetrator's name forgotten more efficiently than the fury he provoked. "That was so out of order, so wrong."
