By my calculations the only players without deals confirmed for this season are Tim Cardall, Ben Harris, Zach Kibirige and Zac Nearchou. Cardall has been in Melbourne recently and Zach is rumoured to be joining the Western Force. Ben seems to be rehabbing from injury.
In terms of next season, as far as I can make out, Charlie Atkinson, Alfie Barbeary, Nizaam Carr, Joe Launchbury, Burger Odendaal, Will Porter, Sam Spink, Jacob Umaga and Tom Willis all have deals. Matteo Minozzi and Ali Crossdale have options to extend their deals at Benetton and Perpignan respectively and the French press are reporting that Dan Robson has agreed a deal to remain at Pau, but this is currently unconfirmed.
