San Antonio Spurs forward Stephen Jackson has been fined by the NBA and warned by his team after making threatening comments on twitter toward Oklahoma City Thunder forward Serge Ibaka. Following a tussle between Ibaka and Jackson's former teammate Metta World Peace, he tweeted, "Somebody tell serg Abaka. He aint bout dis life. Next time he run up on me im goin in his mouth. That’s a promise. He doin 2 much."

The offending tweet has since been deleted from his twitter account.

On Sunday, Jackson apologized for the incident, writing, "I apologize to @SergeIbaka, the NBA, and to all my fans for the comments I made. It was unprofessional and childish. I’m not a thug just a man who speaks his mind. It was not appropriate. I do apologize. Only a man can admit when he’s wrong."

As for Ibaka, he seemed nonplussed by the whole issue, saying "I didn’t see nothing, I didn’t hear nothing." when pressed on it.

The two players will play each other in short order, with the Thunder facing the Spurs next on Dec. 17.
