The New Jersey Nets have been fined $50,000 by the NBA due to minority owner Jay-Z’s illegal contact with Kentucky players, a league source confirmed to SI.com.

The entertainment mogul visited with the Wildcats in the team’s Prudential Center locker room on March 27, congratulating them after a win over North Carolina in the Elite Eight portion of the NCAA tournament and clearly ignoring league rules prohibiting contact with players who have college eligibility remaining.

The meet-and-greet was reportedly captured on video by nearby cameras, sparking an investigation that was first reported by CBSSports.com. The fine was first reported by ESPN.com.

The NBA has dealt with this issue before, most recently when Boston general manager Danny Ainge was fined $30,000 for visiting with Kevin Durant‘s mother, Wanda Pratt, during the Big 12 Tournament in 2007.
