Ellis has experience with Wasps, London Broncos and Ealing Trailfinders Academy.
Fraher said of the signing “Ellis is an exciting player with lots of potential, he’s had a season away from the game but looks in excellent shape.
His Rugby League experience will be invaluable to the midfield and we look forward to working with him”.
McCausland commented “After having some time away from the pitch due to illness and injury, I am now back fighting fit and looking forward to the season ahead with the lads.
As I already know a number of the boys in the team and the skill sets they portray and then to hear the club's ambition, it was a no brainer for me to get involved.
Whether I slot in at 10 or 12 this season, I’m ready to give my all for the Geese and get us back into Nat 2.
The first couple of weeks of preseason have been great, the other lads have welcomed me massively which has helped me get back in the mix. I’m looking forward to getting back on the pitch and tearing it up”.
