Doubt remains over Brisbane spearhead Brendan Fevola on the eve of Brisbane's AFL match against Adelaide at AAMI Stadium.

Fevola has been named in Brisbane's side after spending the week visiting a groin specialist in Adelaide, seeking treatment for an abdominal tear.

Lions captain Jonathon Brown has the same ailment but has been declared a certain starter as his side seeks to break a four-game losing sequence.

Brisbane have confirmed one change to their side, ruckman Mitch Clark recovering from a groin injury to replace utility Matt Austin.

The 15th-placed Crows, with just one win this season, have given 18-year-old onballer Jack Gunston his AFL debut after the forced omission of Bernie Vince and Matthew Jaensch, both suspended by the club for one match for a late night out last weekend.

The Crows surprisingly dropped defender Tony Armstrong after his second AFL match last weekend was productive, while also recalling midfielders Scott Thompson (knee) and David Mackay (groin) from injury.

Adelaide coach Neil Craig said the changes were made despite preparing to confront Brisbane's twin attacking towers of Fevola and Brown.

"We are not going to be able to know everything," Craig said of Fevola's fitness.

"So we have done a little bit different but not a lot - we are a bit conscious of getting a bit too big.

"They (Brisbane) are coming off four losses, so they will be as desperate as us to play tough footy.

"Two key forwards, Brown and Fevola, we have got to be able to handle those two and we need to be at our absolute best to do that."

Craig wants an attitude change from his players after describing Adelaide's capitulation to North Melbourne last weekend as the worst performance of the year.

"That will be our challenge and you would expect to see a different performance this week in the way we go about our footy," he said.

"We just keep pushing that along - high standards, values and competition in footy - and if you don't get it, you just keep pushing forward until you do get it."
