West Coast appear increasingly likely to be without Josh Kennedy for the next two matches as the star forward deals with another hairline fracture.
Kennedy missed last week's loss to North Melbourne after copping a knee to the shin from a teammate at training, and he'll also miss Sunday's western derby against Fremantle.
Coach Adam Simpson says Kennedy's injury is similar to the one he suffered in the round 13 loss to Sydney.
Kennedy missed three matches after that first injury, and he faces a race against time to return for next week's crunch match against Port Adelaide.
The 30-year-old still hasn't returned to training. Instead, he's been doing work on the anti-gravity treadmill and in the gym, as well as some light laps.
"He's getting better. The next week or two we'll hopefully see him back," Simpson said.
"We've just got to get him right. However long that takes, we'll give him."
Simpson said it was unlikely that anything could have been done to avoid Kennedy's latest injury.
"I'm assuming that because it's happened twice, it may be a little bit more vulnerable around that area," Simpson said.
"But I don't think it's a long-term problem for us."
