Natural football collision for me, not reckless imo. Is the bar slightly higher for the second yellow? KF technique of getting yellow out early, not a recommendation for grass roots football, reduces your thinking time, leaves you know where to go, particularly if puts you in second yellow space.
Not seen the incident so more a general point, whilst understanding the concept of taking time before producing a card, there is the flip side, if the tackle comes in, and as ref you are taking the snapshots in your head, click, click, click, and you match up the tackle to what you class as a yc, am content to trust what i saw, I dont need to survey the scene for an injury, or wait for a player reaction etc, if the brain goes,foul, yelllow, I can understand the yellow instantly coming out.
Where you dont want an instant yellow in hand is when you are on the fence in your mind, its those ones yuu maybe take a few secs, whats the feeling, gauge reaction, is there potential flare up, do you need to be quick
As said, not seen the incident so its not specific to the ref last night, but am ok at any level if a referee has decided internally what card to go on occasion, your instincts and snap judgement are sometimes the best route
update have now seen the actual incident, yellow card for me, any of the " what was he meant to do", " how could he avoid it" " he was runnig at speed" etc is all irrelevant, its a certain foul and imo, stonewall reckless, reverse it and had that been gk late of striker ( based purely on the foul, not any reference to dogso), again, its a yc every time.
that aside, what was his first card for? gen question as dont know. If it was for reckless, or persistant, that simply seals your yellow here.
