CHRIS Bridge is a doubt for Wolves' second Easter game at Castleford Tigers on Monday, while Richie Myler will be missing too.
Goal-kicking centre Bridge, who scored the try of the game in the 44-6 defeat of Widnes Vikings, bowed out of the action after 49 minutes.
Wolves' head of coaching and rugby Tony Smith said: "He tightened up in his groin.
"Bearing in mind we've got a game on Monday, we took him off and hopefully he'll recover. Prevention is better than injury."
Scrum half Myler was an absentee against Widnes with a shoulder injury that will also see him miss out at the Mend-A-Hose Jungle.
"Rich succumbed to a shoulder problem," said Smith.
"We had hoped it would settle down but we had to get him off to a consultant late in the week.
"He might miss a few games on the back of it.
"It's nothing major but he might miss the next few weeks, I'd say."
Prop Anthony England withdrew from the Widnes game earlier in the day but Smith hopes he could be one of a number of fresh bodies that he can call on if required for the quick turn around.
Kevin Penny, yet to appear in Super League on his return to the club, is in the mix.
Smith said: "Bridgey is the only person in doubt with injury from today's game.
"Anthony England pulled out this morning with sickness so I'm hoping his antibiotics kick in by Monday and we'll have a fresh body in him.
"We've also got Brad Dwyer, Kevin Penny and Gene Ormsby, so there's a few on standby getting ready for Monday if called upon.
"Penny and Ormsby did play for Swinton today and they came through fine."
