Another of London’s 2019 squad will remain in Super League after agreeing terms with Hull KR.
Back-rower Gee has agreed a one-year deal with the club following three seasons with the Broncos.
He said: “I can’t wait to get started. As soon as I signed I wanted to get cracking with the boys.
“I want to kick on with the boys and get a regular place in the team.”
“I was on my way back from London and Tony Smith rang me to discuss what I was doing next year. I said I was really keen to work under him and it’s a great opportunity.
“I’m looking forward to playing with Jordan Abdull again. He’s a great lad, on and off the field. He’s a great leader and still a young lad, but he can guide teams around the park. I’ve played with Weller Hauraki at Salford too and he’s as experienced as they come.
“I’ve played at this stadium a few times, they’re a loud bunch, and they travel in numbers too, so you can’t beat that really!”
Head coach Tony Smith said: “I am looking forward to working with Matt. He’s got a lot of experience for such a young man and I was really impressed with his work this year I’d go at the London Broncos.
“He’s a handful and is very determined to keep improving his career. He’s spent the last few years down in London and he’s ready to come back up north to pursue a Super League career.
“Matty’s arrival presents a great opportunity for him and for us. He fits our requirements – he’s young, hungry and has a good ability. They’re good ingredients to have and he’s ambitious at the same time.
“Matty can certainly run good lines and has the ability to break tackles. His awareness is very good in that respect to play on the edge but he’s also capable of playing in the middle. He did both within his recent roles at London which makes him an extra valuable asset. He’ll fit in nicely.
“Matty’s coming into what I would suggest are the prime years in which players become hardened regular first-grade Super League forwards. He’s ready for that challenge and has the right desire, maturity and mentality for that. He’s going to be a pleasure to work with.”
