St Kilda's 76-point win over the Western Bulldogs on Sunday might have come at a cost with experienced small forward Adam Schneider suffering another hamstring strain.
The win boosted the Saints' percentage to a healthy 121.88 and lifted them to 10th on the ladder with five rounds left.
But they will likely face fourth-placed Collingwood next Saturday night without Schneider, who was substituted in the third quarter with his second hamstring injury this season.
"We'll assess it over the next 24-48 hours but Adam doesn't have a great history with hamstrings," coach Scott Watters said.
St Kilda's senior players were the driving force behind the victory.
Brendon Goddard, in his 200th match, was outstanding, as were fellow Saints key players Lenny Hayes, captain Nick Riewoldt, Nick Dal Santo and Leigh Montagna.
Coming off a narrow loss to Sydney, the Saints recorded their eighth straight victory against the Bulldogs but Watters said his side needed to lift another notch against the Magpies.
"We really need to pit ourselves and prove ourselves against so many of the quality sides," he said.
"That will be the challenge that goes straight to our leaders. We can't be satisfied with the result tonight. We actually have to take that to another level to keep our season alive. We're looking forward to it."
Watters revealed ruckman/forward Rhys Stanley was edging closer to a return after the 21-year-old strained his hamstring in the Saints' Round 14 loss to North Melbourne.??
"Structurally he's almost our most important player with what he allows other players to do, and that's a pretty big comment considering he hasn't played an enormous amount of footy."??"We'll be very cautious with his return. He's progressing very well. I think some stage over the next fortnight he'd be available," Watters said.
