Coach Kenny Lowe hopes Diego Castro can keep battling through his calf issues to try to get Perth Glory into the Finals Series.
The in-form striker has been dogged by calf problems since the start of the year, with Lowe revealing that though he's carried on playing he's only at around 60 per cent fitness.
He's in danger of missing this weekend's vital clash with Western Sydney, after taking a kick to the calf in the 2-1 win over Melbourne City.
Lowe's unwilling to predict whether his team, who had lost seven of their previous eight games before overcoming City, will make the top six.
But their chances would be greatly improved if they can beat Wanderers, who are sixth in the table and four points above the Glory.
Perth will be boosted for the Spotless Stadium trip by the return of defender Shane Lowry from suspension.
Castro came off 10 minutes from time against City after his calf started to stiffen, though Lowe says the 35-year-old's keen to keep playing.
"He's been carrying a little calf for five or six weeks," added the coach. "But he just wants to play, he just wants to play for the team.
"He's probably (been going at) 60 per cent (fitness), I would say. I think we just (need to) put him in a block of ice for three days, and then chip him out and roll him out on the training ground for the last two sessions."
Castro's fellow striker Adam Taggart is set to get more game time against Wanderers after returning from a hamstring injury as a substitute to head home an injury-time winner against City.
Perth are 1/1 to finish in the top six.
The Glory are 3/1 to beat Western Sydney, who are 5/6 with the draw 3/1.
