Boston Celtics guard Rajon Rondo has been suspended one game without pay for making contact with a game official.  The incident occurred in the third quarter of Boston's 89-81 win in Atlanta on Saturday.  Rondo will serve his ban tonight as the Celtics take on the Knicks in New York.  This is the second suspension of the season for Rondo, who was handed a two-game ban for his involvement in an on-court altercation with Brooklyn on November 28th.  Rondo is averaging 13.2 points and 11.3 assists in 29 games this season.
