Adelaide forward Taylor Walker has had some special skills training to avoid another AFL suspension over his aggressive tackling techniques.
While fellow spearhead Kurt Tippett will miss Saturday's clash with Geelong due to another concussion, Walker returns after a three-game ban for a sling tackle.
It was Walker's second such suspension of the season after he copped two weeks for a similar tackle in round seven against the Cats.
Coach Brenton Sanderson said the 22-year-old had received some one-on-one sessions during the past three weeks to adjust his tackling technique.
"One of the highlights of his form this season is how aggressive he is at every contest," Sanderson said on Wednesday.
"When you marry that up with a technique which we know is not perfect, then he's in trouble.
"So we've worked a little bit on that, just controlling the aggressive but trying to ensure that his technique is perfect as well.
"He's got to adjust his technique and learn to control his aggression and use it in the right way, within the rules."
Before his ban, Walker had booted 37 goals for the Crows and was leading the AFL goal-kicking list.
His return will help Adelaide overcome the loss of Tippett, who will miss the trip to Geelong as he continues to recover from his third concussion in five weeks.
Tippett will spend the weekend with his family in Queensland after having further tests later this week.
Sanderson expected the Crows' star will resume training next week and return for the round-19 match against Essendon, but said the club would take no chances.
"I'm sure we're going to see him back really soon," Sanderson said.
"Hopefully, that's next week but we'll make sure we make the right decision.
"We're not going to force him to go back out and play.
"He's got to be comfortable, the medical team's got to be comfortable and, as coaches, we've got to be comfortable with selecting him, knowing he's going to be OK."
Tippett suffered another head injury in the second quarter of the Crows' win over West Coast at AAMI stadium last weekend and was subbed out just after halftime.
It was his third concussion in just over a month and raised concerns over his long-term future.
But Sanderson said Tippett had already done some running this week and was feeling good.
He had also passed a series of concussion tests prescribed under AFL procedures.
Adelaide will also be without Andy Otten for the next six weeks after he suffered a knee injury against the Eagles.
