ADELAIDE skipper Chelsea Randall is firming as a likely starter for the Crows' crunch semi-final against Collingwood.

Randall suffered a head knock in the dying minutes of the qualifying final loss to Melbourne, and stumbled when attempting to take her free kick, but told medical staff she had merely tripped on her shoelace.

She was widely praised for sitting out the 2021 Grand Final loss with concussion.

"I think she did (trip), it was the worst timing in the world for Chelsea. I think she does it a bit at training and nothing comes of it," teammate Najwa Allen said.

"They're doing all the right things in testing her for concussion, but she's passed the first test and Chelsea's Chelsea. I think we've seen from her Grand Final in previous years that she's not going to lie about something serious like that, so if she genuinely thought it was a danger to her health to play on, she wouldn't. 

"She's looking good for the weekend, which I'm happy about."

Allen said consistency has been a serious issue for Adelaide this season, particularly against fellow top sides Melbourne and Brisbane.

"It's disappointing and it's frustrating, but I don't know if it's worrying, because I know we have the capacity to do it. But it is frustrating to put three goals past a team, then have a lapse where we let them back in the contest," she said.

"For us, in this game and a lot this year, it's a pressure battle. We tend to have these really good quarters – like that first quarter – where we put a lot past them, you know, 'DP' scoring a goal in the first 10 seconds (Danielle Ponter in 19 seconds), and then we have lapses later down the track. 

"I guess the whole game is how well can we hold up against each other's pressure. We tend to hold up really well for a few quarters, and then we drop off. I think that's just going to be the story for the whole finals, it was the story against the Lions a few weeks ago, it was the story last weekend, so it's just how well can we do that."

The Crows will face the Pies for the second time this season, having won by just five points (kicking 2.9 in the process) in round four.

"I saw one of their girls on the weekend, I think it was (Eliza) James, put up four goals herself, so she's probably a little threat, we'll probably stick someone on her for a bit," Allen said with a laugh.

"I think they do well in generating from their backline, taking those handball receives and generating forward momentum. I think if we can cut that out of their game, we'll stop them at the source. 

"Then it's maintaining pressure, putting goals past them when we have the opportunity, and not letting them back in the game, which I think we did a little bit towards the end of the game last time we played them."
