Zak Hardaker will begin training with his new Wigan team-mates next week.
His 14-month doping ban runs until November 7.
But under UK Anti-Doping rules, suspended players can return to training two months earlier.
Although the 26-year-old will not be able to play until next season, he will get the chance to meet many of his new team-mates, settle into the club and work on his fitness.
Hardaker, a former Steve Prescott Man of Steel winner who played at Leeds and Castleford, has signed a four-year deal with Wigan and will effectively replace Catalans-bound Sam Tomkins.
Tomkins missed Friday’s 30-10 victory against St Helens after withdrawing minutes before kick-off with a knee injury.
But Wane expects him to be fit for the visit of Wakefield on Thursday – a game which could see winger Dom Manfredi play his first senior game in more than two years.
