JACK Darling's availability for the NAB Challenge and round one will be determined over the next couple of weeks as West Coast's power forward continues to recover from a foot injury.

Darling suffered a stress fracture in his foot in round 23 last year and the injury continues to plague his pre-season. He spent six weeks in a moon boot before Christmas and was only walking laps at training on Monday.

Eagles coach Adam Simpson said the club was waiting until the next scan on Darling’s foot to determine how the 22-year-old would progress, ahead of the Eagles' first NAB Challenge fixture against Carlton on February 27.

"He'll get a scan in the next couple of weeks to get the all clear to go to the next level," Simpson said.

"We're just being really cautious. We want the bone to heal in the foot as best we can and you can only go by the scans."

Vice-captain Scott Selwood also joined Darling on the sidelines at training on Monday. The 2012 best and fairest had follow-up surgery on his ankle in early December and he is being eased back into a running program over the next week.

Xavier Ellis (AC joint), Jeremy McGovern (hip), Callum Sinclair (finger) and Elliot Yeo (hand) also didn't train on Monday.

Simpson said he expected everyone in his squad to be available for at least one game in the NAB Challenge although he cautioned that the next few weeks were vital for those going through long-term rehabs.

"The next couple of weeks are going to determine a lot of things," Simpson said.

"It's still early January. All of them, I'd hope, would play at least one game at some stage in the pre-season."

Veteran defender Beau Waters is another unknown. The 2012 All Australian has not played since July 2013 due to multiple shoulder surgeries.

He has completed all of the pre-season training to-date although the Eagles are still yet to test him out with full contact work.

Simpson said the tough defender did not have to prove himself in any way, although he was still unsure how Waters’ shoulder would stand up to physical contact.

"I don't need to see him go full contact," Simpson said.

"We've pulled him out of the right drills at the right time and we'll put him in those drills as late as we can.

"I don't think he needs to prove himself with how he attacks the ball or the player with the ball, so I want to give him every chance to play.

"We won't know until the real heat of the battle. I think we're going to wait a few weeks before we test it out."
