MARK Percival is rated as “having a chance” of featuring in Saturday’s World Club Challenge game against Sydney Roosters.

The England centre is a surprise inclusion in Saints’ 21-man squad despite him needing surgery on the shoulder he damaged at Warrington a fortnight ago.

Saints coach Kristian Woolf and his staff will monitor how the player comes through training and assess whether he can play through the pain barrier on Saturday.

Woolf said: “He has a chance of playing. He needs surgery and that happens next week.

“We put him through some contact today to see how it holds up, and today it held up well, but we will have to see how he pulls up tomorrow, but he has a chance.

“There is no danger of making the injury any worse and wouldn’t put him out there if there was any chance of putting his health at risk.

“It is more a matter of whether he can actually play with a bit of pain and get through the game.”

Saints are definitely without Welsh wing Regan Grace which will leave them even further depleted on the left edge.

Matty Costello will go on the wing - and if Percival does not come through - Saints could go with the same left edge that played the second half at Hull - namely James Bentley going into the centres.
