Warrington Wolves head coach Steve Price said: “We as a club are always on the lookout for quality players and it’s great that we’ve been able to sign a player of George’s calibre to a three-and-a-half-year contract.

“He’s a competitive man and an exciting player who has achieved the highest honours in the game here in the English Super League. I’m looking for George to add value and apply pressure to our playing squad during the second half of this campaign.”

Warrington Wolves Chairman Stuart Middleton added: “We are delighted to have secured the services of a world class British half-back.

“Since George’s availability became known to us he became our number one recruitment target. However, bringing him in mid-way through this year proved extremely challenging with numerous complexities attached. Therefore, we are immensely delighted to finally be able to announce this signing to all our loyal supporters and partners.

“I’d like to place on record my thanks to Wigan Warriors for allowing George to join us despite having a first refusal agreement.”

George will be sponsored by Sedulo.
