1. GIDDENS SENT TO NBDL: Boston Celtics rookie guard J.R. Giddens is headed back to the NBA Development League.

The Celtics assigned their first-round draft pick to the Utah Flash for the third time this season. In six games with Boston, he scored four points in eight minutes. With the Flash, he's averaging 17.6 points in 15 games.

Boston took him with the 30th pick of the draft after a strong senior season at New Mexico. Giddens started his collegiate career at Kansas.

2. NBA REFS UNHAPPY WITH FINE: The NBA's referees union criticized the league Friday for fining an official who was involved in a dispute with Boston coach Doc Rivers.

Rivers was fined $25,000 Thursday for his postgame rant two nights earlier in Chicago against Bill Kennedy, who was also docked an undisclosed amount. Rivers complained afterward that Kennedy had stared at him, goading the Celtics coach into receiving a second technical and an automatic ejection. The referees, however, claim that is what they're trained to do, instead of yelling back at the coaches.
