If it's health reasons etc then the club know best however the post Ricardo talked about the timing of it. If we have missed out in using him by having him come back 24 hours late or failing to register in time then that is incompetence of the highest order. I wouldn't be confident at the moment of it not being the latter!
In all reports I have read...it goes he was SENT back. Yes the club is in turmoil......but this is not a great problem.....For example this season....he has played 7 times this season and scored 1. Not prolific at all, not a saviour
I seem to recall that when he was with us, he had problems with depression. May be that's a continuing health problem.
