Sydney Sixers are giving captain Ellyse Perry every chance to prove her fitness for their make-or-break WBBL weekend double-header against Adelaide Strikers.
The Sixers have slipped to fourth place after four-straight losses, the past three without superstar allrounder Perry.
They face the second-placed Strikers in their final two regular-season games on Saturday and Sunday at Sydney's Hurstville Oval.
Two wins would guarantee the Sixers a place in the semi-finals.
And they're hoping Perry can return from the shoulder injury sustained in their last-ball loss to Melbourne Renegades earlier this month.
"I honestly don't know (if Perry will be fit)," Sixers coach Ben Sawyer told AAP.
"The medical staff are doing everything they can. We have to submit our team at 7pm on Friday, so it will be a last-minute decision.
"I saw her run on Sunday after the game (against Perth Scorchers), which was good to see.
"There are a number of steps she needs to get through. The last step is on Friday, so hopefully she gets through that."
Perry believes she will be able to return for the crunch games.
"It's coming along really well," Perry told Australian Community Media.
"We probably won't know for sure until closer to the weekend but fingers crossed.
"I've been in really good hands this last week or so and I'm confident."
Sawyer said he reminded his players in the dressing room after Sunday's second-straight away loss to Perth that fine margins have played a big role in recent defeats.
"I don't think it's (the slump in form) been that long," he said.
"We lost on the last over against the Renegades, and Sunday's defeat to the Scorchers was tight."
The Sixers have beaten the Strikers in all nine of their WBBL meetings to date but Sawyer said that record won't be a factor come this weekend.
"It's irrelevant. They (the Strikers) are playing very well. Sophie Devine has been in great form," he said.
"We hadn't lost to the Hurricanes either before this year."
