Table-toppers Saints will be putting their 100 per cent start to the new Betfred Super League season on the line when they travel to Huddersfield Giants on Thursday night.
It is likely to be a tougher examination of the leaders than originally expected a few weeks ago as on Friday the struggling West Yorkshire outfit earned a morale-boosting victory over Wigan Warriors at the DW Stadium - their first triumph of the campaign.
It will give them a much-needed shot in arm and when top faces bottom it can often lead to a strange scenario in a stadium where the joint title favourites lost 24-16 in June 2017.
Saints' coach Justin Holbrook took the opportunity to rest workaholic skipper James Roby against the London Broncos on Friday as a precaution against a minor problem, but he will be back in the starting line-up this week.
At the same time his replacement Aaron Smith slotted nicely into the hooker role and in what was only his second match in club colours he gained valuable experience which will serve him well in the future.
