Wigan utility Tony Clubb has been ruled out for four to five weeks with a knee injury.
Clubb, 26, was injured in the 44-16 win at Hull last weekend, and is joined on the sidelines by Ryan Sutton, concussed in the same match.
The pair join an ever increasing injury list for Warriors coach Shaun Wane, who has already confirmed that captain Sean O’Loughlin will miss the Magic Weekend.
Clubb has scored four tries in 12 appearances for the Warriors since signing in the off-season from London Broncos.
Prop Sutton is a product of the club’s academy, and has made three appearances in recent weeks.
