The International Rugby Board has revealed new pitch-side concussions assessment procedures that will be trialed this summer.

Both the 2012 Junior World Championship and the Junior World Rugby Trophy will be used by the IRB to implement a blood-bin style procedure for concussion. If a player sustains a head impact injury, then they will be allowed to leave the field for five minutes to go through the IRB's pitch-side concussion assessment. Under the new trial, the referee, the matchday doctor and the team's doctor have the power to recommend that the player undergoes the assessment.

While they are off the field, a player will temporarily replace them - similar to a blood-bin. If the player fails the IRB's test then they will be substituted.

According to IRB chief medical officer Martin Raftery, the new procedure offers "an extra layer of protection" for the players and that the "five minute window is ample time and will deter tactical manipulation".
