Lee Hughes served 3 years for causing death by dangerous driving - he fled the scene so as to avoid being breathalised and handed himself in a couple of days later. His WBA career was over, but he resumed his playing career at Oldham, then Port Vale, then Notts County.
Similarly a goalie...
He'll get a club. Probably not one as big as Sunderland, but offending players always find a way back once they've served their time.
Wouldn't want him at BHA though, even if he was half decent.
