2 days agoNBA refs to start wearing headsets during games
Starting Saturday, NBA referees will begin using headsets during regular-season games for the first time. The league made that announcement Friday, rolling out a two-phase plan to implement the devices. The first phase, which is expected to continue into January, will see referees having the earpiece clipped onto their uniforms - then using it only during instant replay reviews and other stoppages, but not actually during live play.
