SAINTS' 36-10 win over struggling Leeds was achieved at a cost - with Zeb Taia dislocating his shoulder.
The on-song packman went down after hitting the floor after a Mikolaj Oledzki tackle.
Afterwards coach Justin Holbrook said: "He is not good. His shoulder popped out on the field so it is a dislocation.
"He will have to get scans next week, but it is not good.
"We won't know how much damage is done until next week."
Saints also took Mark Percival off as a precaution with a tight hamstring early in the second half.
