Yes, imagine he was struck off for reasons outside of purely footballing.
Interesting claims were made that he's still club captain though. Would have thought that would be removed, as not sure how that ties in with someone who has no future at the club? Not saying he'd completely down tools, but seems odd keeping him in that capacity if he's surplus to requirements. Maybe thats changed since and hasn't been broadcast.
Also going by what I've heard about Scottish football over the past few years, not sure Celtic are able to afford anywhere near Cooks wage, which must be around 30k a week or more.
