WEST Coast coach John Worsfold concedes his side's already-slim finals prospects have faded even further after the Eagles lost their seventh match at Patersons Stadium this season.

The Eagles lost by 34 points to a polished Sydney Swans outfit on Sunday, their fourth loss in their past five matches, and Worsfold admitted his team was not up to the standard of the top four sides, in particular.

"Not sure about finals chances," Worsfold said.

"We'll play out the season and see where we end up. So we'll give it a red-hot go.

"We've certainly been taking it up to the opposition without being good enough to beat them."

Worsfold alluded to the mounting injury toll and his inexperienced line-up as a reason for his side's inability to overcome the Swans.

The Eagles were already missing Shannon Hurn, Scott Selwood, Andrew Embley, Daniel Kerr, Beau Waters and Sam Butler before losing Matt Rosa as a late withdrawal to a back injury.  

"Their midfield, they beat our midfield today," Worsfold said.

"There's no doubt about that. We were pretty happy with the effort our boys put up, but again just a little bit undermanned in that regard, especially with Rosa pulling out late and (Luke) Shuey going down obviously."

Shuey was subbed out of the match at half-time due to hamstring tightness, having missed the past three matches with a hamstring injury.

"[It's] not a recurrence, but it is a tight hamstring," Worsfold said.

"We're not really sure if he's done it or not.

"It's hopefully back-related, which means there's a possibility that when he has a scan there might not be really anything there.

Worsfold used his sub Cale Morton as a loose man in defence in the third term to try and stem the tide after the Swans blitzed West Coast in the second quarter, kicking six goals to two.

"We were in a bit of strife," he said.

"We thought we would try and stop Sydney scoring a little bit and see if we could manufacture some scores going forward.

"So it probably arrested that second quarter dominance they had but not to the level that we needed."

Worsfold was asked whether he would begin to look towards 2014 with regards to resting players that are sore or injured and did not rule out the possibility.

"Not really," he said.

"But as we always do, each player is assessed on their merits, on where they're at, what the risks are of playing on if they're carrying injuries.

"There's no secret that we're monitoring Nic (Naitanui) to see how he's travelling.

"So we'll keep an eye on how he's pulled up from today and things like that and there's a few other players in similar boats."
