Blue card

People who play sports like soccer and rugby are familiar with yellow and red cards, tools for officials to warn or eject players from the game. A blue card is a new addition to rugby’s carding system. A blue card is initiated by an official when there is a suspected concussion. The blue card tool is now used for all rugby activities in Ontario.
