i was playing a match and to start they flicked a overhead and the ref told 2 of us that if we lifted our sticks above our shoulders it was a yellow card. Is it true that no-one can lift their stick above their shoulder not even defenders is this true?

You ar e not allowed to play the ball with your stick above your shoulder accept during a penalty corner defence to stop a ball going into the goal.
