St Helens Head Coach Kristian Woolf confirmed both Will Hopoate and Jonny Lomax will both be sent for scans to discover the severity of their injuries.
Lomax left the field during the first half of their win over Salford. His withdrawal meant James Roby had to play in the halves, with Joey Lussick going in at hooker.
Meanwhile, Hopoate picked up a knock in his first game back after a hamstring injury, which has kept him out since their Challenge Cup win over Catalans.
Woolf: “Lomax doesn’t come off for nothing.”
Speaking in his post-match press conference, Woolf said: “We’ll have to get them both scanned and have a look over the weekend.
“We’ve got an eight day turnaround which is really positive there. Eight days is a long time to sort of turn injuries around.
“Jonny (Lomax) obviously doesn’t come off for nothing. He doesn’t come off very often at all or if ever. As I say, we’ll have a look and hope for good news. It’s his bicep.
“We are hopeful he will be able to play (against Wigan). There was a bit of a precaution there. We will have a look tomorrow and see where it is at.”
Credit for Morgan Knowles for last-ditch tackle
Woolf also praised Saints forward Morgan Knowles for an incredible try-saving tackle right at the end, that secured victory for St Helens.
Chris Atkin intercepted a pass, and was able to run 90 metres, and looked certain to score. But Morgan Knowles, who led the chase back, was able to get him and bring him down. Jack Welsby was then sent to the sin bin for holding down.
However, Saints were able to see out the danger, with Brodie Croft putting a pass down, and with that the clock ran down.
Woolf added: “It was an outstanding chase. I wasn’t quite sure who had the ball, but I thought when they took it that they were gone.
“It certainly looked that way and we’re all running the other way. It’s hard to turn to chase and that’s exactly what Morgan had to do. He had to turn and chase and really stay at that chase. It was an outstanding effort.”
