RFU to trial pitch-side saliva test aimed at determining concussion

Players from the top two divisions of English club rugby are to take part in a major study throughout the coming season that has the aim of developing a pitch-side saliva test to diagnose concussion.
Led by the University of Birmingham and carried out in collaboration with the Rugby Football Union, Premiership Rugby and the Rugby Players' Association, it is hoped the test could also be used to guide return-to-play decisions.
