West Coast will be forced into a third change from the team that lost to the Western Bulldogs after superboot Lewis Jetta pulled up with a calf strain.

Jetta had 15 disposals in his second game back in the side but is now set for a stint on the sidelines alongside Jack Redden (fractured thumb) and Mark Hutchings (hamstring).

“Lewy played quite well after half-time but in the course of that he’s ended up with a calf strain, which we’ll need to manage quite conservatively because Lewy has had quite a history of calf strains,” General Manager – Football Craig Vozzo told westcoasteagles.com.au.

“This will keep him out for two-to-three weeks.”

There was some promising news on Redden after the tough onballer went under the knife on Tuesday.

“There is some chance he still might be available a bit later on this year,” Vozzo said.

“We’re hoping it’s a three-to-four week type injury as opposed to an end of season injury, but we’re waiting on the surgeon’s report.”

Hutchings has suffered a low-grade hamstring which will keep him out for roughly three weeks, while skipper Luke Shuey has made some progress following strains to both hamstrings.

Both midfielders are likely to be available for the first week of finals, should the Eagles qualify, while dual club champion Elliot Yeo could still return in round 18 against North Melbourne on Thursday week.

“We’re thinking it’s another 14 days from here (before Shuey is available) but he elevated his training today and ran pain-free at reasonably good speed, so we’re making good progress,” Vozzo said.

“If we can manage to qualify for finals we’re very confident Luke will be available for the first final.

“Elliot we’re still building. We haven’t ruled out the North Melbourne game, we’re hoping he’s available for that Thursday night fixture.

“But we won’t take any undue risk with Elliot, such an important player for us and the OP (osteitis pubis) injury is such a difficult one to manage.”

Meanwhile, speedy 21-year-old forward Jack Petruccelle is on the verge of returning for his first game since round three following a long-term hamstring strain.

“Given his age with Jack Petruccelle we’ve taken a conservative path and he’s undertaken a huge rebuild with our strength and conditioning staff,” Vozzo said.

“He’s now available for selection this week, fortunately, so he’ll come into consideration at match committee no doubt for the St Kilda game.”

Two players currently undertaking rehabilitation in Perth are Nathan Vardy and draftee Ben Johnson.

Vardy has made excellent progress from his serious compartment syndrome issue and is expected to be fit for the first week of finals, while Johnson is recuperating due to groin soreness.

“Benny Johnson has had some OP symptoms and given he’s a player in his first year we’ve decided to take a really conservative path at the recommendation of our doctor,” Vozzo said.

“So he’s two weeks into an eight-week rest period, which is really frustrating for him and for us, but we’d rather go down that path than put him at risk.”
