Contrasting fortunes for Dangerfield and Sloane

Adelaide star Rory Sloane looks set to face Geelong on Friday night but Cats gun Patrick Dangerfield might not be so lucky.

Sloane, who was knocked out in last weekend's win against Melbourne, completed Adelaide's full training session on Wednesday.

"He looked great today," teammate Andy Otten told reporters.

"He's doing everything he can to play but it will be a doctor's decision."

Sloane passed concussion tests earlier this week and will undergo further testing on the eve of the Adelaide Oval game between the ladder-leading Crows and second-placed Geelong.

"He will do that again tomorrow and see where he's at and if he passes that ... it will be the doctor's final call," Otten said.

"Rory is not going to put himself in jeopardy, I'm sure, and neither is the club.

"We're going to be smart about, he's going to be smart about it. But if he's right, he's right, and if not he won't play, it's as simple as that."

Adelaide defender Jake Lever appears less likely to front against the Cats because of hamstring tightness - he didn't take part in Adelaide's training session on Wednesday.

"He did a bit of work outside the main group today. We have still got a training session tomorrow so we'll see where he's at there," Otten said.

Geelong coach Chris Scott rates Dangerfield only a 40 per cent chance of recovering from his foot injury in time.

Dangerfield suffered the injury early in last weekend's last-gasp victory over Hawthorn, although he still managed to kick a match-winning haul of 5.6 playing as a deep forward.

"While there's still a chance (Dangerfield) can play, we need to be really clear on how late we're prepared to leave it, which in this case is pretty late," Scott said on Wednesday.

"We probably won't make the final call until the day of the game which means he'll travel with us; he's going well enough to do that.

"But as we say quite regularly, and it's not just a line, if there is any risk that he's going to compromise himself towards the end of the season then it would be unlikely he would play."

The Cats covered pretty well for the enforced absence of their other midfield gun Joel Selwood earlier in the year, beating Fremantle and drawing with Greater Western Sydney.

"I'm not one who subscribes to the theory that you take one of the best players in the competition out and you just bring another player in and everything's fine," Scott said.

"Clearly we rely on our best players. I think every team does.

"It would be an interesting challenge for us to perform really well against the best team without Patty.

"Just because we played OK without Joel for a couple of weeks doesn't mean you'd be able to do that every week."
