Adil Rashid has backed Azeem Rafiq's accusation that former England captain Michael Vaughan made a racist remark during the trio's time together at Yorkshire.
Vaughan revealed earlier in November that his name appears in a 100-page report into institutional racism at Yorkshire but strongly denies the allegations against him.
Rafiq brought allegations against Yorkshire, which has already led to the resignations of chairman Roger Hutton and chief executive Mark Arthur.
Vaughan, who played for Yorkshire between 1993 and 2009, allegedly said to a group of Asian team-mates that there were "too many of you lot, we need to do something about it".
Rafiq's version of events were supported by fellow former Yorkshire player Rana Naved-ul-Hassan and now England star Rashid, who had been playing at the T20 World Cup, says he heard Vaughan's alleged comment as well.
In a statement to The Cricketer, Rashid – a Yorkshire player since 2006 – said: "Racism is a cancer in all walks of life and unfortunately in professional sports too, and is something which of course has to be stamped out.
"I wanted to concentrate as much as possible on my cricket and to avoid distractions to the detriment of the team but I can confirm Azeem Rafiq's recollection of Michael Vaughan's comments to a group of us Asian players.
"I'm encouraged by the fact that a parliamentary committee seems to be trying to improve the situation, whether that's holding people accountable or getting changes made at an institutional level.
"These can only be positive developments. I will of course be more than happy to support any official efforts when the time is right.
"For now, though, these matters are of an intensely personal nature and I will not be commenting on them further. I ask you to respect my privacy and allow me to focus on my cricket.
"I want to thank the ECB, the fans and especially my teammates for all of their support. We didn't get the result we wanted in this World Cup, but I hope that the unity of our dressing room and the leadership of our captain will propel us forward to achieve what we deserve in the future."
Stats Perform has approached Yorkshire, the England and Wales Cricket Board (ECB) and Vaughan's representation for further comment.
Rafiq is expected to give evidence in front of the Digital, Culture, Media and Sport (DCMS) select committee on Tuesday.
