Electronic communication

The provision as it is printed, and everything on Ruleside that turns on it.

Players (including substitutes/substituted and sent-off players) are not permitted to wear or use any form of electronic or communication equipment (except where EPTS is allowed). The use of any form of electronic communication by team officials is permitted where it directly relates to player welfare or safety or for tactical/coaching reasons but only small, mobile, handheld equipment (e.g. microphone, headphone, earpiece, mobile phone/ smartphone, smartwatch, tablet, laptop) may be used. A team official who uses unauthorised equipment or who behaves in an inappropriate manner as a result of the use of electronic or communication equipment will be sent off.
