I really can't see this being true. He didn't play a single game for anyone last season did he? It would be a ridiculous signing.
Added to that he's got his testimonial for Warrington against Huddersfield on the 1st Feb, so I really can't see anything being announced about his future until after that?
A 1 year loan deal is perhaps the only way this might be true. Warrington clearly want him off their cap, he'd have signed for Leigh months ago but couldn't because he'd take them over the cap.
