Irving was ending his postgame media commitments when a reporter wished him a “Happy Thanksgiving,” on the eve of the much-loved US national holiday. 

“I don’t celebrate that s***,” Irving said in response, adding: “F*** Thanksgiving.”

The 26-year-old has now apologized for his remarks, putting them down to frustration at his team’s 117-109 loss in Boston.

“I spoke w/ frustration after last nights game and spoke words that shouldn’t be in a professional setting no matter what,” Irving tweeted on Thursday as Americans were tucking into their turkey.

He added in a follow-up tweet: “Meant no disrespect to the Holiday and those who celebrate it respectfully. I’m grateful for the time We all can share with our families. We are always ONE” – including triangle and eye emojis in an apparent reference to the 'Hamsa Hand' symbol of protection he has as a tattoo.
