Sidebottom later posted an apology on Twitter, saying: “I’m truly sorry for any offence caused earlier by my words on @skysportsnews @SkyCricket.
“We should never forget, we must learn. I never meant to say forget. My choice of words were wrong, and an honest mistake. Here’s what I meant.
“I disagree wholeheartedly with discrimination and fully support all investigations and actions surrounding any racial abuse at Yorkshire CCC.
“In my interview with Sky Sports News I used the word ‘forget’. This is not what I meant. I didn’t mean that the situation should be forgotten about, on the contrary, it must never be forgotten. It was a poor choice of words.
“It is crucial that the club, and sport as a whole, learns and adapts to create a truly inclusive environment for all, at all levels. I apologise for any offence caused.
“I am now focused on supporting the playing group at Yorkshire CCC on the pitch.”
