Players may receive advice at any time except during rallies provided play is not thereby delayed (3.4.4.1); if any authorised person gives advice illegally the umpire shall hold up a yellow card to warn him or her that any further such offence will result in his or her dismissal from the playing area.
As a result, STTA is pleased to announce that we will be implementing the new rule with effect from 1st March 2017.
