SAINTS' Mark Percival and Agnatius Paasi both left the field midway through the second half of the win over Hull FC.
Both were precautionary measures with tight hamstrings and coach Kristian Woolf anticipates they will be fine for next week's semi-final against the same opposition.
Percival had had a strong first half, but given his history since last year they took the move to withdraw him.
Woolf said: "They were both precautionary, both tight hamstrings.
"That is probably a result of the travel last week and then the short turnaround.
"That is something we will have to have a look at but at this stage they are both precautions.
"I expect them both to be right for next week."
