RECYCLED trio Cameron Cloke, Scott Harding and Jay Nash will be given an opportunity to stake their claims on a round one berth when Port Adelaide meets West Coast in Saturday night's second round NAB Cup match at Subiaco Oval.

Nash, 24, missed the Power's NAB Cup opener with a thigh strain, while Cloke (shoulder) and Harding (foot) were rested after spending much of the summer in rehabilitation for long-term injuries.

Nash arrived at Alberton from Essendon during trade week and Harding and Cloke were both thrown lifelines in the draft period after being delisted from the Brisbane Lions and Carlton respectively.

Port Adelaide coach Mark Williams said all three players were keen to impress at their new club.

"Last week we played eight players who had never played for the club and now we've got Harding, Nash and Cloke," Williams said on Friday.

"All three are from other clubs and have started their AFL journey without making a dramatic impact, so they've still got a lot of things to prove."

Cloke, 25, was recruited as insurance for the Power's inexperienced ruck department, but must be elevated from the rookie list before he can play in the home and away season.

The decision to place David Rodan on the long-term injury list has created an opening, but Williams said any promotion could be short-lived.

Rodan is unable to play until round two but continues to make remarkable progress in his recovery from LARS (ligament augmentation and reconstruction system) surgery.

The 26-year-old has progressed to agility drills and Williams said the dashing onballer would be eased back into full training over the next couple of weeks.

"David looks great and next week you'll see that he's in every training drill, so that means he's getting very close to being ready to play," he said.

Cloke will carry the mantle as his side's most experienced ruckman against West Coast, with No.1 big man Dean Brogan (quad) rested.

Williams admitted his young ruckmen, also including forward Justin Westhoff and 21-year-old Matthew Lobbe, would have their work cut out against four-time All-Australian Dean Cox and in-form youngster Nic Naitanui.

"They (West Coast) have got two really good ruckmen playing for them and ours are all taking their first opportunities really," he said.

"Our guys will certainly need to do well. They're competing against West Coast but at the same time each of them are competing against themselves as far as who gets to play alongside Dean Brogan."

The temperature in Perth is tipped to soar above 36 degrees on Saturday.

Williams said he expected the AFL to make some concessions to help combat the heat.

"Maybe they'll give you a little extra time at the breaks or even make the substitutes full-time interchange players," he said.

"The AFL aren't dumb and they always work with the clubs, so by the time we get over there that [the rules] could all change around."
