WORRIED Adelaide players say they won't be spooked by the injury to Brent Reilly, who remains in intensive care with skull fractures.

Reilly suffered several fractures to the left side of his skull in a training accident on Monday.

The 203-game veteran was recovering well from emergency surgery but it remains uncertain if he will play again.

"He is going quite well. I know his family is really upbeat and positive about his progression," Crows backman Daniel Talia told reporters on Wednesday.

"Obviously it's still only two or three days after the incident so we don't know too much yet. Fingers crossed that ‘Radar’ is okay and everything is going along well."

Adelaide players and staff were counseled after Reilly suffered the injury when accidentally kneed to the head in a match simulation drill.

But Talia said the incident wouldn't alter the approach of Crows players to their sport.

"It's just one of those injuries that happens," Talia said.

"And as a player, when you put yourself out on the field you realise things like this do happen every now and then.

"The percentage of ugly incidents like this are very minor, so guys will attack the football as normal.

"You put it out of your mind when you're out there and you play the game that you love."

Medical staff are restricting the amount of hospital visitors for Reilly.

"With such a serious injury they don't want too many people seeing him, they want his brain to rest and him not to think too much," Talia said.

"And we need to let his family deal with the incident."

With the retirement of Ben Rutten last season along with Reilly's injury, the Crows could face the loss of 432 games worth of experience in 2015.

Combined with the retirement of Michael Doughty (231 games) at the end of 2012, the club now boasts one of the most inexperienced backlines in the League.

Talia and Brodie Smith are the defence's most-capped certain starters in round one with 76 games each.

The pair are surrounded by the likes of Matthew Jaensch (67 games) Ricky Henderson (64), Luke Brown (46), Kyle Cheney (41), Rory Laird (34), Kyle Hartigan (10). 

Talia said that while there wasn't much experience in the Crows' back half, he was confident the side had the talent to restrict opposition sides this season.

"I think it's a really good opportunity for the guys who are still out on the track. I know as a back six we've been working really well together and there are a number of guys who can step up," Talia said.

"We've got Ricky Henderson back there, Rory Laird, Matt Jaensch – all the guys back there – Kyle Hartigan – all those guys have got a really good opportunity now to play senior footy, play consistent footy and really take that next step.

"We're really positive and when one guy goes down at the club we always know we've got someone to come in and fill a role."

Meanwhile, Kyle Cheney is expected to resume training next week after suffering an episode of an irregular heartbeat.

The former Hawthorn defender was in good spirits at the club on Wednesday but has been excused from training for the rest of the week.
