Every precaution will be taken with Fremantle skipper Matthew Pavlich this week as he bids to play against Geelong at Simonds Stadium on Saturday night.
Pavlich suffered concussion during the second term of last Thursday night's five-point win over Carlton. He was subbed out of the game and doubts were raised over whether he could recover in time for the vital clash with the Cats.
Pavlich was on light duties at Fremantle's training session on Tuesday and ruckman Aaron Sandilands said there would be no risks taken.
"It's real important that we look after him," Sandilands said of his captain.
"Concussions are serious things. He will be monitored throughout the week and we'll see how he goes."
Sandilands said Fremantle's review of the Carlton win had seen a particular focus placed on the centre-square stoppages.
Freo coach Ross Lyon was frustrated that his side had conceded six goals from centre square clearances.
Sandilands and Zac Clarke had 18 centre hit-outs to Carlton's seven but the team lost the centre clearances by three and the Blues scored heavily from them.
"We identified that in our review," Sandilands said.
"We came up against some quality midfielders and a quality group.
"We put some things in place, and we were able to practice that today and over the next couple of days and hopefully we can turn that around this weekend."
Sandilands said Fremantle had worked hard at training over the past couple of weeks following the shock 58-point loss to St Kilda and a below-par performance against Carlton.
"The last couple of weeks we haven't been anywhere near our best, and the best way to turn it around is on the training track," Sandilands said.
"We've been fortunate enough to have a couple of long periods so we can do some more training.
"I think it's going to be more beneficial for us coming into games like this weekend."
Freo have won four of their last five encounters with Geelong including two finals in Victoria in the last two years.
