SAINTS' defeat of Catalans Dragons may have come at a price.

With a leg injury sustained by Mark Percival and possible match judiciary action to come for Luke Walsh and Luke Thonpson, Saints could go into their derby against Saints without upto three of the 17 that defeated Catalans.

“Percival has a leg injury and we’ll just have to assess it and go from there," said Saints coach Keiron Cunningham.

"He’s going to be a big loss for us.

"He was probably one of our most in-form players in the past three or four weeks and he was getting better and better as the weeks went by so it is going to be a blow. We’ve got to find a way of overcoming it.

“Walsh should be up (before the judiciary) and I’d imagine Thompson will be up with the so-called shoulder charge where he hit him with his head.”
