ADAM Simpson will consider redeploying Jeremy McGovern as he starts searching for answers to replace spearhead Josh Kennedy in West Coast's attack.

The Eagles are bracing for news on the severity of Kennedy's suspected calf injury, but the dual Coleman medallist is likely to be facing a stint on the sidelines after hearing a pop when he collapsed in Sunday's loss to GWS.

Simpson expects Kennedy – who has played 103 of the past 105 games – to be unavailable for at least next Saturday's clash with Gold Coast.

West Coast could turn to veteran recruit Drew Petrie to partner Jack Darling up forward in Kennedy's absence, or Simpson might swing intercept-marking defender McGovern into attack.

Forward-ruck Fraser McInnes, who was dropped for the Giants clash after two games as a back-up ruckman, shapes as another option.

Five talking points: West Coast v Greater Western Sydney

"I'm not sure (what we will do), we'll have to look at the depth of our squad," Simpson said post-match.

"We've got options there, we can look at what's at East Perth or we can maybe look at what we do with McGovern."

The Eagles blew a chance to strengthen their top-four spot against GWS, in a game full of momentum swings.

The lead changed hands eight times in the final quarter alone, but the Giants' midfield finally overpowered their West Coast counterparts, largely thanks to Shane Mumford's ruck dominance.

Mumford won 50 hit-outs and GWS controlled clearances (53-32), although Simpson saw some positives in West Coast's contested ball work (106-108) – a weakness in three of the club's four losses.

"The intent and effort was there for the most part. There was some poor execution at stages, a bit of class got us at stages as well," he said.

"We're losing a lot of supply. Our field position at the moment, we're doing a lot of our rebounding from the back half.

"To lose the clearances by (21) and win contested possession … there were some good signs there I thought.

"We saw more of what we liked this week than we did last week."

The Eagles made seven changes – three forced by injury – after the horrible loss to Essendon in round nine, and Simpson was hopeful that Luke Shuey (calf) and Mark LeCras (hip) would be available to face the Suns.

Malcolm Karpany (11 disposals, one goal) showed some promise in his second career game, while Lewis Jetta enjoyed his best game for the club with 28 touches, six inside 50s and two majors.

The former Swans speedster played with intensity and looked dangerous with the ball in an encouraging display following a frustrating season-and-a-half in blue and gold.

"I'm sure everyone's looking for that, including him," Simpson said. "It was really good to see him contribute like he did.

"I think he had 800m gained, and that's what we got him at the club for.

"He's worked through some issues at East Perth and we're pretty positive he's going to come back and have a good influence.

"That's one game and we need to see him back it up."
