PORT Adelaide is bracing for Gold Coast superstar Gary Ablett to return to his best on Saturday after he was held to a season-low 19 disposals against Melbourne.

Suns coach Guy McKenna was annoyed that Demon Jordie McKenzie was able to pay such close attention to Ablett without being penalised by the umpires.

It was Ablett's lowest possession tally since round 16, 2010 when he played for Geelong against Adelaide.

Power forward Robbie Gray predicted Ablett's 'poor' game spelled danger for Port's midfield stoppers.

"Someone like [Ablett's] probably not going to be down for two in a row, so we're going to have a big challenge this week for whoever gets the job on him," Gray said.

"Gold Coast have had a pretty good year and they've got some great players, so we're just looking forward to another challenge.

"They've got a lot of weapons."

The Power have all but sealed up a finals spot, although Gray said the players still weren't thinking about the business end of the season.

If Port Adelaide is avoid making up the numbers in September, he said the club's defensive game had to lift.

Coach Ken Hinkley lamented a goalless first term in round nine when Port last played Geelong, and it didn't get much better last weekend when the Cats ran out to a five-goal lead at quarter time.

Against the best sides in the competition, Gray said sluggish starts wouldn't cut it.

"The defensive side to our game needs to be right on from the word go, we can't allow a quarter or two," he said.

"We had struggles earlier in the year where we were allowing teams to get off to a good start.

"Defensively, that's where our game's got to start and we've shown that at times this year but we've got to bring that from the first minute of the game and bring that for all four quarters."
