Graham played 135 games for the Sharks and joined Wigan on a six-month contract, where he was reunited with former Cronulla lower grade coach Stuart Raper.
?I always wanted to come back to the NRL and I?m looking forward to joining Wests Tigers,? Graham said.
?Tim Sheens is someone who I?ve always respected and it will be great to work with him,?
?Wigan has been great to me, but the NRL has always been where I wanted to continue playing.?
Head Coach Tim Sheens says Graham is a great athlete and has a tremendous attitude.
?Nick is a class playmaker who takes the pressure off the halves,?
?His work-rate for a forward is tremendous,?
?His experience will certainly help with the younger guys that are coming through the grades?.
