Anthony Griffin will be demanding a strong performance from his side despite being all but certain of playing finals football after North Queensland's loss on Thursday night.

Only a defeat by more than 37 points and victory to the Dragons over the Bulldogs on Sunday will see the Panthers slip out of the top eight but Griffin has brushed off the idea that his side will be able to put in anything less than 100 percent.

"Another game to go and it's really important we play well and win this game," Griffin said.

"We've been finishing the year off really well and we were very disappointed last week with the loss against St George.

"For us, it's a do-or-die game and that’s how we're approaching it. Whatever happens after the game we'll worry about it then."

Coming into last week off the back of seven straight wins, Griffin was disappointed with the outcome but was content with the attitude of the players.

"I thought it was a really strong performance physically and attitude-wise," Griffin said.

"We just didn’t play the way we wanted to play and how we needed to, to win that game.

"But it's still been a really good build up in to this time of year and tomorrow night is really important."

Griffin will be without the services of boom fullback Dylan Edwards after he suffered a knee injury against the Dragons. Despite lamenting his absence, the coach is confident that his replacement will step up to the plate as has often been the case this season.

"It’s hard when you lose a key position player at any time of the year," he said.

"As has happened all year for us, whoever we've given a job to they've always done it.

"You need that in your club and your team to be able to compete at this time of year.

"It's opened up a really good opportunity for Dean Whare. Obviously Dylan's done a good job but we've got total confidence in Dean tomorrow night."
