Blue cards set to cut from sin bin trial as agenda set for Loch Lomond summit

The cards were set to be unveiled as the method used to signal a temporary dismissal in trial protocols originally scheduled for publication on February 9, a move which would have marked the biggest change in managing player discipline in the professional game since the introduction of red and yellow cards for the 1970 World Cup. However, there was a largely negative reaction when reports about blue cards surfaced on the eve of publication, and the International Football Association Board, which sets the game’s laws, opted to delay publication of the protocol.
