The fact that Jennings got sent off for foul and abusive language seemed absolutely ridiculous at the time as this would happen in every match if the refs took that view. Now that there is a booking scandal, I would think the limelight would fall directly onto the referee firstly, due to how bizarre a decision it was. Jennings reaction both on and off the park suggested he was pissed off to be red carded at such a late and crucial stage in the game. I said in the immediate aftermath of the game that the ref should be investigated as there was something weird going on. It now seems like a possibility.
As for not appealing, I would urge Motherwell to view the footage again and you can clearly see the ref telling Jennings to "Get tae f*ck". I realise two wrongs don't make a right, however, if they stick by the red card decision, then I'd hope anyone who uses foul and abusive language in the future is shown a straight red, else it is a case of one rule for some and one rule for others.
