Ferrelli had sent a tweet to the star saying he’d ‘better come back a lot stronger and quicker to make up for this past season’, the New York Daily News reported.
In response, Stoudemire, who is currently suffering from a hand injury, fired off a private message saying: ‘F*** you. I don’t have to do anything f**.’
NBA officials then launched an investigation after Ferrelli posted a screen grab of the message on the social networking site that started trending.
According to reports, Stoudemire has since apologized to the fan in a subsequent direct message. “I apologize for what I said earlier,” Stoudemire allegedly messaged. “I just got off the plane and had time to think about it. Sorry bro!! No excuses. Won’t happen again.”
