Wigan winger Tom Davies faces three months on the sidelines after suffering a dislocated and broken ankle.
The England Knights international left the field in the first half of Wigan’s 36-10 defeat to rivals St Helens on Good Friday.
Davies was on the deck for five minutes before being taken to hospital, while half-back Jake Shorrocks left the action late on following a collision with Dom Peyroux, who was then sin-binned.
On Davies’ injury, Warriors coach Adrian Lam said: “It is both dislocation and broken.
“His ankle was completely out of its socket and at a right angle at one stage. If its dislocated then it will probably be eight weeks but if its broken then it will probably be 12 weeks.
“He will be out for around three months so he will join a few of our players on the sidelines.
“I think nine of our starting team are out now. He got on the happy gas and went to hospital straight away so he will be in an operation as we speak.
“Liam Marshall might be available [on Monday] but he is not 100% either. We have got some really good wingers at this club but he is coming back from five weeks out, so he might be good for Monday.”
Jake Shorrocks suffered a neck injury but Lam believes he won’t be out for long, while Tommy Leuluai also suffered a calf injury and is doubtful for Monday’s trip to Salford.
And Lam admitted that injuries are taking their toll on the Warriors, who sit 10th in the Super League table.
He added: “We didn’t have a full training session as a group this week.
“We had 12 training of the players who played this week, so it’s difficult to get cohesion there as a team. You have to be there to see how hard it is but we have got to try and stay positive.
“We are probably going to have to bring in two of the academy players again now so we need to focus on the positives until the next match. We have brought through Amir Bourouh and he will probably play on Monday.
“There are still some senior players in the team and those senior players have got to make sure we get through the next four to six weeks and get some wins.”
