NBA puts immediate ban on midcourt sideline TV cameras

— -- In an effort to protect players and referees the NBA has banned midcourt sideline television cameras effective immediately, sources told ESPN.com.

The edict comes a little more than a week after referee Scott Wall rolled his ankle when he tripped over a midcourt cameraman in the  Memphis Grizzlies' 102-101 win over the  Denver Nuggets in Denver on Jan. 21. LeBron James suffered an ankle injury tripping over a midcourt camera during Game 1 of the Eastern Conference Finals last season in Atlanta. They are two examples of accidents involving the cameramen in recent years.

The ban will affect national television games where cameramen were permitted to sit on each side of the floor at midcourt. Those positions were able to get high-quality low-angle shots of both the floor and the benches.

Saturday night's Cleveland Cavaliers- San Antonio Spurs game, televised nationally on ABC, didn't have the sideline cameras.

The National Basketball Referees Association had requested a change recently, sources said. As teams increase the number of 3-pointers and the depth of them, referees have been moving farther and farther out to create angles to officiate. This left them more susceptible to the cameramen near midcourt.

The league has made several rule changes in recent years to attempt to make sidelines safer for officials and players. Cameramen were moved on the baseline to create more room around the basket and basket standards have been moved back to allow maximum space to land under the rim.
