ADELAIDE's Brodie Smith says players who don't take Sunday's match against Greater Western Sydney seriously enough could find themselves in the SANFL next week.

The Crows are unbackable favourites to beat the Giants after the expansion side was demolished by Hawthorn last weekend by 162 points.

But Smith said that after their competitive performance against the Crows in round four, GWS demanded respect and those who didn't provide it might be dropped.

"Last time we played them they pushed us out here, so we know what they're capable of," he said.

"They're a good contested ball team, like us, so we know we've got to battle in there.

"We can't go there with big heads.

"We've got guys that are going to be coming back from injury and, again, guys that will play well in the SANFL, so every week's a challenge to play well."

After a poor nine-disposal effort against Fremantle in round 10, Smith found himself on the outer at West Lakes.

He was forced to return to the SANFL and line up for last year's premiers Woodville/West Torrens to find form.

Smith accepted the challenge and in rounds 12 and 13 collected a total of 55 possessions; earning back his starting position in Adelaide's best 22.

The 20-year-old said that with the talent and depth on offer at West Lakes, his experience was a warning to others.

"I had to keep my head up and play a couple of good weeks of footy to get back in the side and I did that," he said.

"There's so many guys playing good SANFL footy at the moment, so the pressure's coming from all angles.

"You saw Timmy Mac (Tim McIntyre) last week, a rookie, he's been playing good footy and he came in so there is that pressure that you've got to be right at the top of your game or you will drop out."

Adelaide held its main training session of the week on Thursday behind locked gates at AAMI Stadium, minus small forward Jared Petrenko.

Ian Callinan was said to have made it through the session without incident while Kurt Tippett "was running laps and kicking goals", but Smith maintained coach Brenton Sanderson's line that the decision to name the star forward would be left until the last minute.

Michael Doughty will remain in Adelaide this weekend despite wife Sara already having given birth to the couple's first son, Max.

Smith said the oldest player on the Crows' list was never going to play against the Giants at Skoda Stadium.

"I think the plan was always for him to have the week off and stay with his wife," he said.
