Joe Greenwood was taken to hospital after suffering an injury in Wigan's Magic Weekend loss to Warrington.
The England forward left the action during the first-half - for the second successive week.
Adrian Lam says he suffered suspected broken ribs, which may sideline him for around a month.
But Wigan will get a more detailed recovery timeframe once he has undergone scans.
Thomas Leuluai missed the game with a shoulder injury but Lam expects him and several other players to be fit for Wigan's next game in two weeks, against Hull KR.
