NBA referees will answer questions about calls in real time over Twitter in a selection of games for the rest of the season, starting with two games next week.
During Monday's Golden State Warriors at Los Angeles Lakers game on TNT and Wednesday's San Antonio Spurs at Philadelphia 76ers game on ESPN fans can tweet @OfficialNBARefs or use the hashtag #RefWatchParty to get responses from officials who are watching the game.
Members of the National Basketball Referees Association first tried out the concept last season during a Finals game.
