IRB moves to strengthen concussion tests

The decision represents a 100% rise on the five minutes that are currently allowed for team doctors to make a judgement on whether a player has sustained a concussion.
International rugby’s governing body has also revealed that two specific sections of the Pitch-side Suspected Concussion Assessments (PSCA) tool have been expanded for the elite game, with the memory test being “strengthened” and the balance examination “altered”.
