NBA referee Zach Zarba sparked controversy on Tuesday night when he was caught on camera appearing to dap up Minnesota Timberwolves guard Anthony Edwards in the middle of a Western Conference playoff game. Edwards had just made a key defensive play, swatting away a shot from Suns guard Bradley Beal. Zarba’s gesture was met with surprise from many, including Edwards’ teammates and social media users, who questioned the appropriateness of such a move during a live game.
