Aussie scrum-half Luke Walsh is back in Saints' 19-man squad ahead of Friday night's home game against neighbours Widnes Vikings after a four-match absence due to injury.
Centre/winger Matty Dawson is also included in the squad but both Adam Swift and Dominique Peyroux are missing through injury.
Head coach Keiron Cunningham said: "We have three really tough games coming up before the split. We will be treating all of them like a Grand Final but naturally only focusing on one at a time, starting this Friday.”
Cunningham added: “We've simply got to concentrate on week-by-week rugby because you don't know what the immediate future will bring.
“Widnes will provide tough opposition and will be buoyed by their impressive win at Leeds on Sunday.”
