SAINTS boss Keiron Cunningham will not take a gamble by playing Australian scrum-half Luke Walsh in Sunday's World Club Challenge against South Sydney.

The star scrum half recovered from leg and ankle injuries which have kept him out since last July but a virus prevented him making a return to full training in time for last Thursday's Super League round-two game at Salford.

"He won't play," Cunningham said. "He's not ready.

"It's unfortunate he can't be part of such a big event but I don't think we can risk him.

"He's a world-class player and he'd have a big influence on the game but we've a very long season and we'll probably need him on many occasions down the track."

It means Saints will continue for the big game with Jon Wilkin at seven.
