FREMANTLE is expected to select at least one more first-year player against Collingwood on Saturday, with assistant coach Chris Scott declaring Zac Clarke and Hayden Ballantyne were both in the selection mix.

Clarke travelled with the main group on Thursday morning, but Ballantyne, Des Headland, Michael Walters, Adam Campbell and Kepler Bradley were notable absentees.

Scott said Clarke, 19, had been in line to debut for the past month and Collingwood's two-pronged ruck division would be considered when deciding if he plays his first AFL game at the MCG. 

"He's someone we're really keen to bring into the side," Scott said.

"We don't expect big things from him first up, but when he does get his chance, he's going to give us something that we haven't had for a long time, and that's two genuine ruckmen.

"And Collingwood do have two pretty seasoned ruckmen."

A former stet junior basketballer in Victoria, Clarke has averaged more than 16 hit-outs a game in the WAFL. 

Scott said the No.37 draft pick would develop into an imposing ruckman, but also had the potential to build an engine similar to champion Eagles ruckman Dean Cox.

"It's difficult to compare him to current AFL players, given he hasn't played yet," Scott said. 

"He's an outstanding aerobic athlete. I'm not comparing him to Dean Cox as a player, but in terms of his aerobic capacity he has the ability to develop that type of run.

"And he's also going to fill out – we think he's going to be a very good size.

"He has some aggression already. Once he has the body and he really develops physically, when he matches that with his aggression we think he's going to be a pretty imposing player."

Ballantyne was set to be unveiled against Port Adelaide in round 11 before a back compliant sidelined him.

The 21-year-old has played just one game of WAFL football this season after having wrist surgery pre-season, but Scott said the exciting small forward had impressed on the track.

"We're very keen to get him in the side, there's no secret about that, and he's the type of player we need," he said.

"But he hasn't played much football.

"It's just a question of whether we need him to play some good football in the WAFL or whether we bring him back on the back of the really good training he's been doing."

Brett Peake and Clayton Hinkley, who both missed Fremantle's narrow loss to Geelong both travelled, while Scott said Headland was line ball to return from a quad injury.
