The NBA is reviewing comments made by Dallas owner Mark Cuban regarding his interest in acquiring LeBron James this offseason.

Cuban expressed his desire to add James in an interview with CNN Money this week.

The interview was published Thursday and Cuban indicated that while the Mavericks can't sign James outright, a sign-and-trade may be a possibility.

Teams are not allowed to comment on potential free agents prior to July 1, when the market opens.

The league has a tampering rule that can result in a fine of up to $1 million and a loss of draft picks or other assets.
