Rajon Rondo has been suspended one game without pay for making contact with a game official and failure to cooperate with a league investigation, it was announced today by Stu Jackson, NBA Executive Vice President Basketball Operations. It is the second suspension for Rondo this season, after serving a two-game suspension for his shoving Kris Humphries on Nov. 28.

The latest incident involving official Rodney Mott occurred with 3:19 remaining in the third quarter of the Celtics’ 89-81 victory over the Atlanta Hawks on Saturday night at Philips Arena. Rondo will serve his suspension tonight when the Celtics play the Knicks at Madison Square Garden.

There’s a secondary angle to the story. Hawks GM Danny Ferry is being fined $15,000 for approaching the NBA referees and handing them a videotape of the incident after the game.

The league has a strict rule about players or team officials approaching a referee after the game, for any reason, so Ferry was hit with the fine by the league.
