Old Collegians will be without star midfielder Bodie Hibberson for its elimination final against Panmure.
Hibberson sustained a hamstring injury in the third-quarter of his side's 21.21 (147) to 6.5 (41) win over Russells Creek.
Playing coach Nick Sheehan said the injury would rule Hibberson out for three to four weeks at best.
The Warriors mentor said it was a hard loss to take.
"He's one of our better players," he said.
Hibberson, who has played 10 matches this season, has been in the Warriors' best six times.
Sheehan is expecting a good contest against the Bulldogs on Sunday.
"Panmure are going to be hunting us so we've got to be on our toes early," he said.
"We've got to win the contested footy in the middle of the ground."
He said the Warriors would put a bit of work into stopping Bulldogs playing coach Chris Bant.
Apart from Hibberson's injury, it was a positive day for Old Collegians.
Sheehan got the four-quarter effort he has been seeking all season.
The Warriors scored seven goals in the first quarter, three in the second, five in the third and six in the fourth.
"It gives me good confidence going forward," he said.
"We were good with our hands around the stoppages."
But what impressed Sheehan most was how his side handled the second-quarter.
He said Creek had the momentum in the second-term before the Warriors swung it back their way.
The first-year mentor said it was good to regain control.
Sheehan said Ben Turner-Dwyer, who was back from suspension, played well.
"I was really happy with him," he said.
"He went to Andy McMeel.
"He did his role on him."
Sheehan was also impressed with Aaron Williams' return game.
"He was a great target up forward," he said.
