Azeem Rafiq is 'ashamed' of an antisemitic message he sent as a teenager.
The Barnsley man gave testimony to MPs in Westminster this week about the racist abuse he received at Yorkshire, who have been suspended from hosting England matches while several key figures have resigned or been suspended.
But messages have now emerged of a conversation with fellow cricketer Ateeq Javid in which Rafiq used antisemitic language.
Rafiq posted on Twitter: "I was sent an image of this exchange from early 2011 today. I have gone back to check my account and it is me – I have absolutely no excuses.
"I am ashamed of this exchange and have now deleted it so as not to cause further offence. I was 19 at the time and I hope and believe I am a different person today.
"I am incredibly angry at myself and I aplogise to the Jewish community and everyone who is rightly offended by this."
