The NBA has fined the Houston Rockets for making public comments on Dwight Howard during the league’s moratorium period.

The NBA free-agency period opens July 1, but the league undergoes a moratorium on trades and free-agent signings until July 10. During that period, teams are allowed to negotiate with free agents and speak among one another for trade purposes, but they are not permitted to make public comments.

Since Howard made his decision to sign a four-year, $88 million deal with the Rockets on Friday, the team has broken that code of silence multiple times. In particular, Houston general manager Daryl Morey has made multiple public comments—both on his Twitter feed and to media—after the offseason’s most prized target informed Houston he was headed there.
