Zak Hardaker has been handed a Super League lifeline after signing a four-year deal with Wigan Warriors.

The 26-year-old is serving a 14-month UK Anti-Doping ban, which ends in November, following a positive test for a banned substance.

Hardaker was found to have benzoylecgonine – the main metabolite of cocaine – in his system following Castleford Tigers' clash against his former club Leeds Rhinos last September.

He was dropped for the Grand Final as the Tigers fell at the last hurdle and was later sacked by the club.

Rumours surfaced that the Warriors were pondering a move for the full-back, and Wigan have now confirmed he will join the club from November 8.

Head coach Shaun Wane told the club's website: "Zak is an outstanding competitor and a hugely talented individual who will understand the culture at our club. 

"He is the opposition name who, when we preview his team, is always the main danger. Now he is one on our team and that is pleasing for everyone involved.

"His early return to training will assist his transition back into the sport but he will not be available to play in the 2018 Super League season."

Chairman Ian Lenagan added: "This wasn't a decision that we made lightly. We recognise the serious nature of this incident and our choice in offering this opportunity should not be seen as condoning his actions in any way.

"We had extensive conversations with Zak and his family before making our offer. We encountered a man who, after eight months of reflection, openly admits that he has made a series of significantly poor decisions over the past few years. 

"Crucially, we also saw someone who recognises that this is the final opportunity to focus on delivering the achievements his talent should generate."

Hardaker has won three Grand Finals and two Challenge Cup medals, and was named Super League Man of Steel in 2015.
