The rules for 2010 are:
Quote At least 7 home grown players.'"
Huby, Owen, Westerman, Shenton, Boyle, Massey, Thompson, Arundel, Cording, Davies, Gledhill, Walker
Quote No more than 5 quota players.'"
Sherwin, Sargent, Chase, Widders, McGoldrick
Quote No more that 6 overseas trained players inc quota players.'"
Evans (UK passport) + quota 5
Quote Rest of squad to be from players trained within same federation.'"
So we have filled all our quota spots, meaning that no overseas players will be coming next year, unless we get rid of one of our quota players, which looks pretty unlikely.
For 2011 we can only have 5 overseas players, so it looks like one of Sherwin, Sargent and Chase will be leaving at the end of next year - I imagine it'll be Sherwin.
