Something similar has been tried in a few club run tournaments, when as soon as a team reached five non-walking offences, the player committing the fifth was blue carded and sin-binned for two minutes, so team affected as opposed to player. The referee has to do the "totting up", and one unfortunate player, who maybe hasn't committed an offence at all is penalised. When refereeing at a County tournament, I tell players clearly on the second offence, after awarding the free kick that it is his/her second offence before restarting play.

Hi Russell Stait thanks for your feedback here. One of the things tested in the trial was whether the sanction was a blue card or a penalty, and which one of these proved to be a bigger deterrent. A lot of the sentiment shared was that the ethos of Walking Football is to keep players active and issuing blue cards to someone who may well have committed their first non-walking offence seemed overly harsh. From a safety lens, could reducing a team by one player also cause overexertion to the remaining players on the pitch? These were all considered and discussed within the focus groups.
