On his return to the Sale line-up against their rivals from London, the 24-year-old struggled from the outset, missing two early penalties before handing the goalkicking duties over to team-mate Mike Hercus.
He went off injured early in the second period, and Saint-Andre later admitted his fly-half was going through a difficult spell.
But the Sharks boss insisted the club would do all they could to help Hodgson rediscover his form - and secure a place on the Lions' summer tour of New Zealand.
"I don't think it (confidence) is very high at the moment," said Saint-Andre.
"The first kick he missed, the second kick he missed, and then he started to have a bad groin and stopped kicking.
"He is a good player, he is very important in our team and we will do our best to help him and I am sure he will be back to his best very quickly.
"He has showed such good things with us all season. I remember at the beginning of the season he kicked very well when we beat Leicester. And when we beat Wasps away he kicked a drop-goal from 45 yards.
"He needs to stay focused and get the confidence back."
