Yeah I'm sure Hougaard is still contracted because I think Henson was brought in while Hougaard is out.  As it stands if Sarries were to keep Henson then they certainly don't need Hodgson.  They'd have Hougaard, Farrell and Henson.  Hodgson would be better off staying at Sale imo, they are a decent club that just need a kick up the arse sometimes.
