NEW YORK (AP) - The NBA has fined Knicks guard J.R. Smith for his Twitter exchange with Detroit Pistons guard Brandon Jennings.
The league says Friday's $25,000 penalty was for ''directing hostile and inappropriate language to another player via his Twitter account.''
Smith's latest social media flap - he also was fined $25,000 by the NBA last year for a racy tweet - started Wednesday after Jennings made a critical comment about Smith's little brother, Chris, who also plays for the Knicks.
Jennings noted that Chris Smith is in the NBA though Pooh Jeter and Bobby Brown aren't. J.R. Smith, saying he is tired of people disrespecting his little brother, responded with a couple of tweets, including one that appeared threatening toward Detroit and was later taken down.
