The NBA is investigating the Twitter feud between New York's J.R. Smith and Detroit's Brandon Jennings over the presence of Smith's brother, Chris, on the Knicks' roster, sources close to the process told ESPN.com's Marc Stein.
The teams meet Tuesday in Detroit, but the league office is expected to rule before then whether anything said between the two can be deemed threatening.
On Wednesday, Jennings sent out the following tweet, which was later deleted: "Wait wait wait JR smith brother is in the NBA but @PoohJeter & @BBROWNLAU isn't. Call me hater but not Rollin!!!"
Shortly after the Knicks' win over the Atlanta Hawks on Wednesday night, J.R. Smith responded with a tweet appearing to threaten to send his "street homies" to Detroit, presumably to confront Jennings.
Smith also wrote that he had "no respect" for Jennings.
J.R. Smith said on Thursday night that he didn't mean to threaten Jennings with his tweet.
