New signing: Lee Mossop re-joins Wigan Warriors after Parramatta Eels exit
A product of Wigan's youth academy, Mossop debuted for the Super League club in 2008 and made 111 appearances before switching to the NRL in time for the 2014 season.
Having missed out on a Finals place with Parramatta, Mossop returns to Wigan with the option for a further year on his contract in the club's favour.
The 25-year-old has been released from his contract with the NRL side to assist with their salary cap constraints and, having had shoulder surgery in recent months, he is likely to make his return to action in February.
"I want to thank Parramatta Eels for giving me the chance to play in the NRL and experience a different lifestyle in Australia," Mossop told the club's official website.
"I have enjoyed my time there, however felt it was the right time to return to the UK.
"Wigan was always going to be my first choice and I am really happy that we have been able to agree a deal. I owe a lot to this club having come through the youth system.
"The squad is a bit younger now and I hope to be able to pass on my experience to some of the other players. I was at the Grand Final last month cheering the boys on and hope to be back there again next season."
Mossop joins Joel Tomkins in returning to the club and head coach Shaun Wane added his delight at being able to secure another high-profile signing.
"I rate Lee Mossop highly and am pleased to see him re-join us," he added. "As soon as I heard that he might be available, I asked Kris Radlinski [general manager] and Ian Lenagan [chairman] to see if it was possible and I am grateful that they have done just that.
"I am pleased also for Lee showing loyalty to the club. Having seen the fans welcome Joel Tomkins back earlier this year, I am looking forward to seeing them give Lee a great reception at the DW [Stadium] next season."
