In the "football world" they are totally different things though. Jennings is under investigation for a crime that brings the game into question, and could lead to match fixing charges. If Motherwell have any thoughts of him being guilty then no, he shouldn't play. He should be suspended - if possible without pay - but if Motherwell believe him then I see why nothe shouldn't be allowed to play.
Of course, there are bodies within Football that can take it out of our hands, if the Crown Office actually do press charges - guilty or not
