Ellison, who made 10 appearances for the club last season, began his career at Wigan and has had spells with Swinton, London Skolars and Oldham.
He said: “I’m delighted to have re-signed for the club, Tony gets the best out of me and motivates me. I really enjoyed being at the club last season, there are some really good people at the club, I’ve got good friends here which was another factor for re-signing.
“The club has got good facilities and it’s the little things that they look after so we can just concentrate on playing rugby. There were a few clubs interested in me, but I wanted to remain here and it just felt right to re-sign for the 2014.”
