I think they Should sue to SFA for defamation as they have implied he's cheated to gain an advantage. If you are accused of simulating a foul then that can be construed to mean you tried to gain an advantage by deception and or cheating and that is not what keatings has done. It would be easy to get a physio or specialist in bio mechanics to analyse the video and prove from an expert medical point of view how the body reacts when it's hit at speed. Then go after them for the character assassination. The SFA really have opened up a can of worms over this and surely tunnocks are not liking the bad PR as it's their name in most of the stories.
