The Cleveland Cavaliers and Miami Heat have been warned to hold up the "three-sign" to their eye during their game in Rio De Janeiro.
In America it's just a celebration for a player that just knocked down a huge three pointer. In Brazil that's not exactly how it works.
Holding up the "three goggles" in a certain way in Brazil could be mistaken for a graphic reference.
The memo the NBA reportedly sent out to both teams warns the players to be careful with what they do during the exhibition. For the preseason game the Cavaliers and Heat have to find another way to celebrate three pointers.
