San Antonio's Stephen Jackson was fined $25,000 by the NBA Sunday for a "hostile statement" he sent to the Thunder's Serge Ibaka over Twitter. San Antonio Spurs swingman Stephen Jackson has been slapped with a $25,000 fine "for issuing a hostile statement directed to Serge Ibaka in a Twitter message," the NBA announced Sunday. "I apologize to Serge Ibaka, the NBA, and to all my fans for the comments I made," Jackson tweeted. Jackson apologized to Ibaka on Twitter on Sunday, calling his post "unprofessional and childish." The announcement by NBA executive vice president of basketball operations Stu Jackson followed a Sunday statement issued by the Spurs organization condemning the 34-year-old guard/forward, who has played for seven teams during a 12-plus-year NBA career. There was grabbing of jerseys, blowing of whistles and separating by teammates; beyond that, as ESPN color commentator Jeff Van Gundy said, "That was nothing."
