Corica has failed to recover from the hamstring injury he suffered during the 1-0 loss to Gold Coast United and will miss the match against the fifth-placed Glory, much to his disappointment.
"You know obviously I wanted to be fit for this match but it hasn't worked out that way," he said.
With the Hyundai A-League taking a break last week due to the round of international matches, there was hope that Corica would have recovered for the trip West but the team's coaching staff didn't want to risk their skipper before he was fully fit.
"I felt it (the hamstring injury) a little bit yesterday in training and the coaches think it's best if I have an extra week off to recover and get it 100% right."
Corica had not been able to participate fully with the rest of the team in training since the Gold Coast match but he is still doing his fair share of training, looking ahead of next weekend's home game against the Newcastle Jets.
"I started doing a little bit of bike work to keep my fitness going and then now I've stepped it up a bit," Corica said. "I'm doing a fair bit of running and in and out of cones and ball work and stuff like that to keep my heart rate up and keep my fitness where it should be."
Corica - who will not be travelling with the team to Perth - is confident that his team will be able to perform.
"We've been working on how we're going to play against them (Perth) and we've had obviously two weeks now with the weekend off last week and everyone's 100% fit except for myself."
He is also aware of their need to perform in order to maintain first place on the ladder.
"Our away season hasn't been the best so far. We need to pick up a few more away points and hoping to do that this weekend in Perth."
With the Sky Blues heading to Perth on Friday, Corica intends to use his time productively and boost his chances of being able to join the rest of the team when they return to training next Wednesday.
"Hopefully I will join in with the team next Wednesday and be ready for the Newcastle game," he said.
"It gives me an extra week and a half before the next game (against Newcastle) so I'm pretty confident that I'll be ready for the next one."
