Jay-Z's visit with the Kentucky Wildcats may land him in hot water with the NBA.

According to reports, the locker room visit made by the rapper, who sat courtside at the game held in Newark, N.J., and spoke with the players following their victory over the North Carolina Tar Heels Sunday, was a violation of the rules. Because Jay is a minority owner of the New Jersey Nets, he is therefore barred from having contact with amateur players who have not yet been chosen for the draft pool.

Since two Wildcats members -- Brandon Knight and Terrence Jones -- are potential lottery picks, the NBA has launched an investigation into the nature of Jay's invitation to the game, and his visit to the locker room.

The hip-hop mogul is friends with William Wesley, a noted basketball agent, which is likely the reason why he was behind the scenes. Hoopla aside, the players certainly had no problem meeting Hov. "It was crazy. I kind of had to do a double-take. I didn't expect that at all. I just had to get a picture with him," said Kentucky guard Darius Miller.
