World Rugby has confirmed that the Contego Sports N-Pro head guard may not be used at any level of the game as the product has not yet been independently and rigorously trialled or tested in a competition environment. It does not currently comply with World Rugby Regulation 12 or Law 4. 
Given the potential advertised player welfare benefits of the product, World Rugby is examining the possibility of implementing a controlled trial to test the product’s safety and performance independently and robustly. It is intended that data from this trial will provide evidence to allow a responsible recommendation to be made on the product’s efficacy. 
With player welfare at its heart, this is a standard process of due diligence and is implemented whenever a medical product featuring new technology has been developed. A successful outcome would result in the product being awarded the necessary ‘approved by World Rugby’ mark. 
Throughout the product’s development, the manufacturer has been aware that until such a scientific approval process has been undertaken, World Rugby cannot permit the use of the N-Pro product in competition at any level.
