The NBA is reportedly investigating whether teams tampered in order to secure some of the earliest free-agent signings this offseason.

According to ESPN's Zach Lowe and Brian Windhorst, the investigation began after the NBA's Board of Governors meeting in Las Vegas this month. The investigation is reportedly expected to include interviews with "players and possibly agents and team employees."

Charlotte Hornets owner and labor committee head Michael Jordan mentioned the possibility of changing the free-agency rules in the next collective bargaining agreement in what was described as a "tense" owners meeting.

Teams were permitted to begin speaking with free agents on June 30 at 6 p.m. ET, and the moratorium was lifted July 6, which was the date on which signings could become official.

NBA Commissioner Adam Silver reportedly encouraged owners to express any concerns they had with the free-agency process, which led to several suggestions for how it can be improved.
