SAINTS centre Mark Percival will miss the World Club Challenge clash with Sydney Roosters with a sternum and shoulder injury.

The England three-quarter sustained a 53rd minute injury when he tried to halt Warrington's big back row Ben Murdoch-Masila in Thursday's defeat.

Coach Kristian Woolf will have a number of options ahead of Sunday's trip to Hull FC, with Matty Costello an option alongside a number of players who have played back row - Joe Batchelor, James Bentley and Dom Peyroux.

Woolf said: "He is going to be a couple of weeks, that is for sure.

"It will be a bit of a loss for us for a little while.

"He has hurt his shoulder and sternum and has had some scans.

"And we have got to go and meet with the doctor to figure out what our next moves are.

"He is brave - he has done that a number of times and Ben Murdoch-Masila is a big, powerful man - so there is no question of his bravery."

With Tommy Makinson likely to be back after recovering from shoulder surgery, Kevin Naiqama can return to the other centre spot.

Woolf will weigh up Percival's replacement as the week progresses.

"Matty Costello is an option, but we can also move blokes around as well.

"We have a long turnaround to think about those ­— with a few guys who have played there before.

"We are also hopeful that guys like Tommy Makinson, Kyle Amor and Morgan Knowles will be available this week," he said.

"Alex Walmsley has some chance for this week but at the same time we have to weigh up the risk and if that is too high then he won't play.

"It has recovered quite well and we are fortunate that he felt it before he put himself in a position where it could have been a much longer term injury.

"Having the turnaround of a couple of extra days to make a decision."!
