NBA referees are waiting to see if they will be called for a technical foul after their foundation held a non-sanctioned two-day conference last weekend, USA Today is reporting.

Several NBA officials, including coaches and front office personnel, were either invited or scheduled to attend but were not allowed by the league to participate.

The conference was open to referees of all levels. The conference included panel discussions involving NBA referees and members of the media and an awards dinner.

"I don't anticipate any repercussions," said Lamell McMorris, executive director of the National Basketball Referees Association and the referees union spokesman. "We've given them no reason. There remains the question why (they took) this position for something that's good."

The NBA, in a letter to the union dated Aug. 17 and signed by Richard Buchanan, the league general counsel, said it was concerned the conference would be open to the public and referees would be discussing NBA business and operations.

When asked why the NBA did not sanction the conference and prohibited league officials from participating, NBA spokesman Tim Frank said, "It's an internal matter and we're not going to comment."
