Shaun Ainscough is set to make his first Super League appearance of the season for Wigan on Friday.
Marsh and Walker called into 22
Wigan winger Shaun Ainscough is poised to make his first Super League appearance of the season for the Warriors against Harlequins on Friday night after being recalled from his loan spell at Castleford.
The 20-year-old Ainscough scored 17 tries in his first 10 appearances for Wigan last season, but has so far been unable to force his way into contention under new coach Michael Maguire.
He went on loan initially to Widnes and more recently Castleford, where he has scored four tries in seven appearances, but has returned to the DW Stadium to plug the gap caused by injuries to Amos Roberts and Darrell Goulding.
With Andy Coley, Thomas Leuluai and Harrison Hansen still sidelined, Maguire has also called up centre Stefan Marsh, 19, and forward Johnny Walker, 22, for what would be their Super League debuts.
