DESPITE having just one win on the board, Fremantle coach Mark Harvey is looking to stabilise his team in a bid to beat Carlton on Saturday.

His bid for stability hasn’t been helped with Roger Hayden hospitalised since the three-point loss to the Western Bulldogs on Sunday with a collapsed lung and with a hamstring injury to Marcus Drum, but those two are likely to be the only two outs.

Young forward Chris Mayne and defender Antoni Grover will replace them as Fremantle looks for its second win of the year.

"Roger is getting out of hospital today and will miss three to four weeks,” Harvey said on Wednesday.

“He had trouble breathing, but we didn’t know the extent of it at the time, and his direction and rebound will be something we will miss. That's where someone like Heath Black can hopefully fill the void.

"Marcus Drum will train and then we will assess how his hamstring is. He's 50-50 at this stage. We are still waiting for the scans and that's fair dinkum.

"Regularly playing guys at AFL level is what I mean by stability and getting them able to play in that intensity and environment more. Apart from replacing the one or two injuries, we'll go in with the same side."

With Grover returning to strengthen the back-line, he will likely take Brendan Fevola to allow Luke McPharlin to join Tarrant and Pavlich in the forward set up.

With Pavlich and Tarrant kicking eight goals between them against the Bulldogs, Harvey would like to see other players step up in the midfield, as Garrick Ibbotson and Rhys Palmer have.

"Pav is Mr Fix It and has to do everything. The decision to go into the middle is up to Matthew and he brought it upon himself as captain of the footy club to do that," he said.

"Tarrant and Pav were dangerous forwards for us, so we have to find different ways around needing Pavlich to go into the middle. Hopefully in time once we evolve with our midfield rotations, we can get that right balance no matter the situation."

Chris Judd looms as the man in-form tagger Ryan Crowley will resume hostilities with after the pair had numerous Western Derby battles over the years.

"He (Judd) made a big decision in his football to return home, he's captain of the club and we will have to sit on him heavily and let him know he's in the game," he said.

"Crowley has been fantastic the last few weeks at playing on those sorts of guys and he will probably get dealt the hand again. Crowls has really come of age to be elite in every area to run with those guys and should be praised."
