Widnes will be without leading try scorer Krisnan Inu for up to three months after he suffered a broken leg over the Easter weekend.
Inu, 31, was forced off during the Good Friday defeat to Warrington and underwent surgery on Wednesday.
The off-season signing from Catalans has scored six tries and nine goals in eight appearances for the Vikings in 2018.
Just to clear the air on those wondering, since I’ve just had my op a few hours ago, now I’m pretty sure I can say it’s about 10-12 weeks on the sideline. Sorry @WidnesRL fans.. I’ll be back even stronger then before. Let’s keep supporting our team and this great club!! pic.twitter.com/htqJavTmVI
